Use Renovate for markdown-link-check updates

[andrzej-stencel]

The version of markdown-link-check took has been pinned to a specific version in #11605 due to a bug in the most recent release tcort/markdown-link-check#368.

Ideally the version of the tool should be updated automatically by Renovate bot by creating a pull request on every new release of the tool. This would allow us to control the version used and only ever use a version that actually works.

Looks like nothing needs to be changed, Renovate is already doing its job: #11608.

Not exactly true. It's true that Renovate correctly creates a PR to update markdown-link-check, but the problem is, the check-links job is not run for this PR (see

opentelemetry-collector/.github/workflows/check-links.yaml

Line 34 in 3b7f68d

if: ${{needs.changedfiles.outputs.md}}

). As a result, there is no way to know if the update does not break the tool.

We need to change the check-links job to also be run when the tool is updated - e.g. when package.json file is changed.
