Add branch information in renovate-debug PR tag

[secustor]

Tell us more.

Right now we are adding only minimal information to the debugging tag in PRs

Example:

<!--renovate-debug:eyJjcmVhdGVkSW5WZXIiOiI0NC4zLjIiLCJ1cGRhdGVkSW5WZXIiOiI0NC4zLjIiLCJ0YXJnZXRCcmFuY2giOiJtYWluIiwibGFiZWxzIjpbXX0=-->

# which contains following information: 
{"createdInVer":"44.3.2","updatedInVer":"44.3.2","targetBranch":"main","labels":[]}

It would be helpful for tooling and agents to identify problems and gather context if we could add information like:

• Job / Trace ID / LOG_CONTEXT
• BranchCache ( What contains this PR )
• ?

Downsides

The downside will be that it will consume precious characters for PR bodies and will likely become a problem on big PRs

So this could maybe become a self-hosted option.

A configurable renovate-debug option sounds good to me 👍🏻
