Regex for renovate is not picking up devcontainer.json

All those renovate comments are not being read

Renovate is at least looking now! However, it's not working correctly for all things:

• Failed to look up github-releases package renovate/renovate
• Failed to look up deb package moby-cli
• Failed to look up deb package moby-buildx

#288 fixes the first one. I thought you might have had a fix for the second two already?

[sdwilsh]

I tried a bunch of things for the latter two, but no luck. Might be best to see if we can use a GitHub release for that.

This continues to be broken, and I just removed the versions we had pinned in #319
