docs: Miscellaneous docs cleanup (#6742)
Fix spelling errors, API doc inconsistencies, and formatting issues.

* Fix several spelling errors.
* Prepend / to v1/event/list path in Watches.
* Rename script handlers to match Watch type.
* Remove /v1 path prefix on service health API endpoints.

Makes request path consistent with the rest of the HTTP API
documentation which does not include the /v1 prefix.

* Fix bracket formatting issue on Telemetry page.

The HTML codes used for brackets inside of the code block are not
interpolated, and are shown as literal strings.

Replace the numeric HTML codes with the intended character value to
fix display formatting.

Also placed variable reference on agent/options.html inside code block
for consistency with the presentation of other options on the page.

* Add missing word to Coordinate.Node docstring.

Resolves #6014
