run vale in docker

[crazy-max]

Description

Atm vale only runs in GitHub Actions:

docs/.github/workflows/build.yml

Lines 71 to 80 in c69c0b5

	vale:
	if: ${{ github.event_name == 'pull_request' }}
	runs-on: ubuntu-24.04
	steps:
	- uses: actions/checkout@v4
	- uses: errata-ai/vale-action@reviewdog
	env:
	PIP_BREAK_SYSTEM_PACKAGES: 1
	with:
	files: content

With this change we are now able to run vale locally using bake:

$ docker buildx bake vale

When running in GitHub Actions it will change the output format so reviewdog can create GitHub Annotations on pull request event. Having a dedicated step running reviewdog avoids the clunky output we have when running vale-action. Now are just displayed issues related to the pull request opened.
