This fixes a bug when azure-provider tries to fetch original content of a renamed file and fails since the file doesn't exist in base yet.
Also handles case when `diff_type` includes multiple actions as `edit, rename`.
This can be improved to fetch the actual old content using the old path before renaming, but IMO for azure devops since its dying anyway, this fix should be enough.

Update `_parse_pr_url` method in `pr_agent/git_providers/bitbucket_server_provider.py` to handle URLs with `/users/`.
* Add logic to check for both `/projects/` and `/users/` in the URL path and process them accordingly.
* Modify the method to raise a `ValueError` if neither `/projects/` nor `/users/` is found in the URL.
* Update the `workspace_slug` to include a `~` prefix if the URL contains `/users/`.
Add test case for URL with `/users/` in `tests/unittest/test_bitbucket_provider.py`.
* Ensure the new test case verifies the correct parsing of URLs with `/users/`.
