Modify commit message for config migration

[z0rc]

How are you running Renovate?

GitLab self-hosted

Was this something which used to work for you, and then stopped?

I never saw this working

Wanted end result.

Renovate's config.js has configMigration: true. I want to modify commit message for config migration commits to match our gitlab commit rules.

What you tried so far.

I tried to look for suitable attribute in packageRules to match configuration migration events and edit commitMessage there, but wasn't able to find working solution.

Alternatively there is option onboardingCommitMessage, so maybe similar option can be introduced for config migration, like configMigrationCommitMessage.

I suggest using a RENOVATE_X_ variable within here: https://github.com/renovatebot/renovate/blob/a1f79bcf39f7dcf0951ed4260092ff8407dcfbbd/lib/workers/repository/config-migration/branch/commit-message.ts#L36C1-L38

I'm reading https://docs.renovatebot.com/self-hosted-experimental/ and cannot find suitable variable. Do you suggest such variable should be added? Or am I missing something?

I mean add a new variable for this purpose
