Add option to skip/ignore specified git remotes during operations

**Is your feature request related to a problem? Please describe.**
Permission errors constantly appear in logs when attempting operations on git remotes where access is restricted.

**Describe the solution you'd like**
Add ability to specify remotes to ignore/skip during git operations, preventing access attempts and error messages for those remotes.

**Describe alternatives you've considered**
Manually removing restricted remotes (not ideal as they're needed for reference)

**Additional context**
