[DOCS] Changelog test

[lcawl]

This PR is just for testing purposes.
It tests the docs-builder changelog commands, for example with elastic/docs-builder#2843 checked out:

1. Check out Enhance changelog bundle and remove commands with github release workflow docs-builder#2843
2. Refresh the tooling. In the docs-builder repo, run:

   ./build.sh clean
   ./build.sh publishbinaries

3. In the apm-agent-dotnet repo, set up the changelog configuration file:

    /path/to/GitHub/docs-builder/.artifacts/publish/docs-builder/release/docs-builder changelog init

   Fill in the relevant fields, like the default product ID, bundle directory, bundle repo and owner, etc.
4. Generate changelogs for the PRs mentioned in the GitHub release. For example:

   /path/to/GitHub/docs-builder/.artifacts/publish/docs-builder/release/docs-builder \
   changelog add --release-version v1.34.0 \
   --repo apm-agent-dotnet --owner elastic \
   --output ./docs/changelog --config ./docs/changelog.yml

5. Generate a changelog bundle. For example:

   /path/to/GitHub/docs-builder/.artifacts/publish/docs-builder/release/docs-builder changelog bundle --release-version v1.34.0
