[Gitlab, Codeowners] Issue with section name with space

[vtexns]

How are you running Renovate?

Self-hosted Renovate

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Gitlab, 40.48.5

Please tell us more about your question or problem

As #32061 was released, we started testing and discovered that if the section name contains the space character, it will be parsed wrong way but according to the gitlab docs, it is allowed

CODEOWNERS file:

[Code Owners] @username1 @username2
*
