Enables creating branches without remote tracking

Introduces a `noTracking` option to the `checkout` operation, allowing `git checkout -b --no-track` to be used.

The `GitRepositoryService.switch` method now supports this option, which is leveraged by the `branch create --switch` command. When creating a local branch from a remote branch with a different name, the command will now use `--no-track` to prevent automatic setup of a remote tracking branch.
