Problem

.rubocop_todo/**/*.yml contains auto-correctable (RuboCop) offenses (grep -hr auto-correct .rubocop_todo -A 1 | grep "^[A-Z]") which can be fixed automatically.

Implementation guide

Resolve auto-correctable rules which are enabled by letting RuboCop auto-correct them automatically 🎉

Verify that the you are working on is already enabled. See also #369268 (closed)
Pick a offense from The List below e.g. Layout/ClosingHeredocIndentation
Create a branch (e.g. 239356-abc/fix-Layout/ClosingHeredocIndentation)
- Info: Using this issue ID (239356) in a branch name will add required labels and reference to this issue in the new merge request.
- Info: Using your username or initials (e.g. abc/ above) in the branch name will help to prevent branch naming clashes with other contributors also working on this issue.
Delete the rule from the corresponding .rubocop_todo/ YAML file (for example https://gitlab.com/gitlab-org/gitlab/-/blob/fdeea9247566ca45fece68605a838ebc659b62db/.rubocop_todo/gitlab/rails/safe_format.yml)
Auto-correct RuboCop offenses via e.g. bundle exec rubocop --autocorrect --only Layout/ClosingHeredocIndentation
Check changed files and adjust if needed
- Suggestion: In order to keep MRs short one can fix 10-15 files in one go. Depending on the amount of changes in the file.
Commit and create a merge request
- Hint: You can use Fix <Cop/Name> offenses as git commit message
- Info: Community contributions can use git trailer Changelog: other so they are attributed in CHANGELOG.md
Mention this merge request in this issue
