  The changelogs will be in the same order as commit-types input.

  If the type doesn't match any of the provided commit-types input keys, The default-commit-type input will be used instead.

• The category is optional and can be anything of your choice.

• The flag is optional (if provided, it must be surrounded in square brackets) and can be one of the followings:

Commit messages not matching the format mentioned above will be ignored in the changelog output.
