CI changes for Dependabot PRs

[Guillaume Smet]

Hi,

To reduce our CI costs and avoid running CI useless for some Dependabot PRs, I have put in place a validation for running CI for PRs coming from Dependabot.

We have to set up a limited number of people for this feature so I picked a few of you.

I don't mind approving myself so don't do it if you don't want to.

The idea is that we should ask ourselves "do we really want this?" before running the CI. For instance, for Kotlin, we know we have a lot of manual work to do and we can't accept the Dependabot PR so it's useless to run CI for this PR.

For anything coming from mvnpm, there's a manual check to do and often Phillip group them in a PR he writes, so again no need for testing.

Let's iterate on this. If you're not happy with it, complain to me, if you don't know what to do, I'm always around :).

Thanks.
