[Bug] sync_community_teams.py adds additional lines with the same pattern

[TimidRobot]

Description

sync_community_teams.py adds additional lines with the same pattern

Reproduction

For example:

• https://github.com/creativecommons/vocabulary/pull/1101
  • https://github.com/creativecommons/vocabulary/blob/7ebe41326a758e119b8943c7c7995d3f0e18d622/.github/CODEOWNERS#L5-L6

    * @creativecommons/technology @creativecommons/ct-vocabulary-maintainers @creativecommons/ct-vocabulary-core-committers
    * @creativecommons/ct-vocabulary-collaborators
    

Expectation

About code owners - GitHub Docs:

If you want to match two or more code owners with the same pattern, all the code owners must be on the same line. If the code owners are not on the same line, the pattern matches only the last mentioned code owner.
