Add release automation for rules_cc

Tracking issue: https://github.com/bazelbuild/rules_cc/issues/268

This CL adds a release workflow for rules_cc. It also adds a ci.bazelrc file that is used to configure Bazel on CI.

The release workflow is based on the release workflow for rules_proto. It uses the same release script, which generates a source archive and a release notes file. The release notes file is used as the top of the release notes for the release.

The ci.bazelrc file is used to configure Bazel on CI. It sets the --announce_rc option, which causes Bazel to print a message to the console whenever an option is set. It also sets the --disk_cache option, which tells Bazel to use a disk cache for downloaded external artifacts. This can help to speed up builds.

Finally, the ci.bazelrc file sets the --test_output option to errors. This causes Bazel to print test logs to the console, even if the tests pass. This can be helpful for debugging test failures.

## Using bzlmod with Bazel 6 or later:
1. [Bazel 6] Add \`common --enable_bzlmod\` to \`.bazelrc\`.
2. Add to your \`MODULE.bazel\` file:
\`\`\`starlark
bazel_dep(name = "rules_cc", version = "${TAG}")
\`\`\`
## Using WORKSPACE:
\`\`\`starlark
