Dependabot settings: remove the Automated testing label.

[priethor]

What?

Updates the dependabot settings to add less labels to PRs.

Why?

Following up on #52760, PRs should only have one label of each type. Moreover, the Automated testing label has been updated to [Type] Automated testing and doesn't exist anymore.

How?

By removing the Automated testing label from the dependabot settings.

This seems fine.

It looks like two [Type] labels are currently being added, automated testing and build tooling (see #51461). It's likely adding what's closest to the inaccuracy being fixed here. For what it's worth, I think GitHub Actions related changes could affect either, or even both. Build Tools will not always be the correct label.

If they're both added, it forces someone to think about which one is more appropriate before removing the second one. Maybe instead of deleting Automated Testing, adjust it to [Type] Automated Testing?

I'm not the person using these labels for anything currently, though. So I defer to you all.

Thanks for the insights, @desrosj ! What triggered me to open this PR is that I have recently renamed Automated testing with the Type prefix, too, as part of #52760, which prevents merging PRs with more than one type of type-related label. The idea was to prevent Dependabot PRs from having two type labels. However, if we are unsure which one applies, as Dependabot PRs still need to be manually approved, we could let the reviewer adjust the labels at their discretion.

Given that you usually review those PRs, would you find that too much of a hassle? I'm happy to close this PR if you prefer that approach 🙂

I'm fine with this for now. There is an error being shown on every Dependabot PR because the label no longer exists.
