Introduce "Green-means-go" Renovate PR Messages

[samdanaei]

Background

We are establishing a structured dependency update process for both the Tentacle and Halibut repositories. As part of this initiative, we will introduce a "Green-means-go" PR message, similar to the dependency update procedures used in Octopus Server. This will allow developers to approve certain dependencies with minimal scrutiny, while ensuring that other dependencies receive the appropriate level of review.

Results

When a Renovate PR is created, the PR message will inform the developer if it is relatively safe to merge. This applies only to packages with good test coverage, ensuring any issues are easily detected during TeamCity builds.

The process enables developers to add new "Green-means-go" rules. For example:

{
  matchPackageNames: ['Nsubstitute'],
  prBodyNotes: [
    ...preCannedPrNotes.greenMeansGo,
    'Used extensively throughout tests.',
  ],
}
