do not display an indicator when a git branch is up to date with a remote

https://github.com/romkatv/powerlevel10k/issues/2361 requested an indicator for
up to date branches, which was added in
20323d6f8c.

Since then, 3 users complained about the new indicator:

- https://github.com/romkatv/powerlevel10k/issues/2377
- https://github.com/romkatv/powerlevel10k/issues/2380
- https://github.com/romkatv/powerlevel10k/issues/2361#issuecomment-1630731045

On one hand we have one request to add a feature. On the other hand we have
three complaints about the feature's existence. The feature is going away.
