feat(openobserve transform): Add OpenObserve as an officially supported sink

[chaitanya-sistla]

This PR adds OpenObserve as an officially supported sink in Vector's documentation. OpenObserve utilizes an HTTP-based API for data ingestion, and this PR proposes updating the documentation with an example configuration for users to follow.

No new functionality is required, as the current HTTP sink already serves the purpose effectively. The primary goal is to improve user experience by offering clear guidance for setting up Vector with OpenObserve, ensuring confidence in its usage as a supported observability solution.

type = "http"
inputs = [ "source_or_transform_id" ]
uri = "http://localhost:5080/api/default/default/_json"
method = "post"
auth.strategy = "basic"
auth.user = "[email protected]"
auth.password = "v9Ca7qHaMKELlDtU" (fake)
compression = "gzip"
encoding.codec = "json"
encoding.timestamp_format = "rfc3339"
healthcheck.enabled = false

Why This Matters?
By officially documenting OpenObserve as a supported sink, we provide clear setup instructions for users, allowing them to confidently configure Vector for OpenObserve.

Closes: #21514

@jszwedko could you help me review this? Is anything pending from my end?

Hello, this PR doesn't require any code changes and it seems more like a user guide on how to configure an existing sink. It feels like https://github.com/vectordotdev/vector-demos might be the right place for this. Or it could live under a new Community section in https://vector.dev/guides/

int_tests is a GitHub job that detects if a branch contains changes to integration tests. Since you didn't added any integration tests dedicated to openobserve you should revert all changes to .github/workflows/*,

make sense

👋 Left some nits. Since it affects the generated docs, you can run make generate-component-docs && make check-component-docs to regren and validate.

@pront I don't have the file in my PR, do you want me to open a new PR or just add the file in my existing PR? https://github.com/vectordotdev/vector/blob/master/.github/workflows/semantic.yml#L182

Feel free to ignore this, but you can sync your fork, git merge origin master and it should be there.

More importantly, the changelog format is off and is blocking this PR from merging.
