Pull request title checks are always case insensitive

[RapGeneral]

I have the following configuration:

mergeable:
  - when: pull_request.*
    validate:
      - do: title
        must_include:
          regex: \[(Patch|Minor|Major|No-Version)\]
          message: "Please ensure the title is prefixed with a SemVer identifier in PascalCase ([Major], [Minor], [Patch] or [No-Version])"

Expected: Only PRs which contains pascal case SemVer identifiers will pass
Actual: All casings pass.

I looks trough the docs and couldnt find any way to configure the casing.

Looking trough the code it apperantly forces the i regex flag (meaning case insensitive).
The solution is to add

regex_flag: "none"
