Provisioning: Fix repository URLs for generic git type (#118285)

For generic git repositories (non-GitHub/GitLab/Bitbucket), remove the
'/tree/{branch}' segment from URLs. Different git hosting platforms
have different URL patterns, so we return just the base repository URL.

Changes:
- getRepoHrefForProvider: Return clean base URL for 'git' type
- getBranchUrl: Return clean base URL for 'git' type instead of empty string
- Updated test to expect base URL without /tree/ segment

Example:
Before: http://localhost:3001/owner/repo/tree/main
After: http://localhost:3001/owner/repo
