* docs: Remove 1.0 beta warning about HCL2.0 docs
* docs: multiregion is not beta anymore either
* docs: scaling isn't beta
* docs: neither is events api
Mainly note that block labels need to be string literals, and that decimals without a leading significant digits aren't acceptable anymore (e.g. .9 are required to be 0.9).
Dynamic blocks can be used here, but feels too much of a hack, or a hammer to highlight it here, specially given the error reporting and debugging isn't so straightforward. I'd advocate internally for relaxing the restriction and allowing expressions in block labels instead.

During testing we discovered old versions of Nomad and Consul seemed to
prevent Envoy from accepting new connections while the Nomad agent was
being upgraded.
* use full name for events
use evaluation and allocation instead of short name
* update api event stream package and shortnames
* update docs
* make sync; fix typo
* backwards compat not from 1.0.0-beta event stream api changes
* use api types instead of string
* rm backwards compat note that only changed between prereleases
* remove backwards incompat that only existed in prereleases
* systemd should be downcased
* containerd should be downcased
* spellchecking, adjust list item spacing
* QEMU should be upcased
* spelling, it's->its
* Fewer exclamation points; drive-by list spacing
* Update website/pages/docs/internals/security.mdx
* Namespace is not ent only now.

Expand `volume` and `volume_mount` sections to describe how to use HCL2
dynamic blocks and interpolation to have finer-grained control over how
allocations get volumes.
Previously, every Envoy Connect sidecar would spawn as many worker
threads as logical CPU cores. That is Envoy's default behavior when
`--concurrency` is not explicitly set. Nomad now sets the concurrency
flag to 1, which is sensible for the default cpu = 250 Mhz resources
allocated for sidecar proxies. The concurrency value can be configured
in Client configuration by setting `meta.connect.proxy_concurrency`.
Closes#9341
If Docker auth helpers are used but aith fails or the image isn't found, we
hard fail the task. Users may set `auth_soft_fail` to fallback to the public
Docker Hub on a per-job basis. But users that mix public and private images
have to set `auth_soft_fail=true` for every job using a public image if Docker
auth helpers are used.
* Remove Managed Sinks from Nomad
Managed Sinks were a beta feature in Nomad 1.0-beta2. During the beta
period it was determined that this was not a scalable approach to
support community and third party sinks.

Before, upstreams could only be defined using the default datacenter.
Now, the `datacenter` field can be set in a connect upstream definition,
informing consul of the desire for an instance of the upstream service
in the specified datacenter. The field is optional and continues to
default to the local datacenter.
Closes#8964
Add more detailed HCL2 docs, mostly lifted from Packer with tweaks for Nomad.
The function docs are basically verbatim taken from Packer with basic string substitutions. I commented out some for_each details as the examples are mostly driven towards Packer resources. I'll iterate on those with better Nomad examples.
The API is missing values for `ReadAllocs` and `WriteAllocs` fields, resulting
in allocation claims not being populated in the web UI. These fields mirror
the fields in `nomad/structs.CSIVolume`. Returning a separate list of stubs
for read and write would be ideal, but this can't be done without either
bloating the API response with repeated full `Allocation` data, or causing a
panic in previous versions of the CLI.
The `nomad/structs` fields are persisted with nil values and are populated
during RPC, so we'll do the same in the HTTP API and populate the `ReadAllocs`
and `WriteAllocs` fields with a map of allocation IDs, but with null
values. The web UI will then create its `ReadAllocations` and
`WriteAllocations` fields by mapping from those IDs to the values in
`Allocations`, instead of flattening the map into a list.
