Build: changing docs docker image to prevent setting up frontend devenv. (#28670)

* Build: changing docs dev-environment

I have added a new image that will include the auto-generated frontend docs so you don't have to generate those locally prior to running the doc container. This has a dependency on this PR: https://github.com/grafana/website/pull/2744 and that we publish a version of the `grafana/docs-devenv` image.

* will ignore everything (even symbolic links)

* fixed spelling.

* added newline.

* updated image name.
