I have a monorepo and my config requirement is

1. It should raise separate MR for node.js LTS runtime update, which should update .nvmrc and docker ex: node:20.13.0-alpine3.19. It is good to have if it can update the gitlab-ci.yml node image version as well.

2. It should raise separate MR for major and (minor & patch) updates.

3. It should only update minor and patch for node-fetch, eslint, prettier and any package containing eslint or prettier in its name, ex: eslint-config-prettier.

Current issue, the config below creates separate MRs for minor and patch updates.

My current configuration.

1. You need to ensure that the updates get different branches assigned e.g. by overwriting depName.

2. You are not setting separateMinorMajor outside of your folders.

3. Your packageRule for packages does overwrite updateType and matching it. You want to disable updates you can do this with ( enabled: false )
