[Feature Request] Support pull requests in personal spaces in bitbucket server without requiring any URL hacks

[JimiHFord]

If you use a repository hosted in a personal space in Bitbucket Server (e.g. https://bitbucket.company-server.url/users/username/repos/my-repo/pull-requests/1, you'll get:

ValueError: The provided URL 'https://bitbucket.company-server.url/users/username/repos/my-repo/pull-requests/1' does not appear to be a Bitbucket PR URL

A workaround/hack our team found was to modify the url from this:

https://bitbucket.company-server.url/users/username/repos/my-repo/pull-requests/1

to this:

https://bitbucket.company-server.url/projects/~username/repos/my-repo/pull-requests/1

(i.e. Change users to projects and add a ~ in front of the username)

This works, but ideally the first URL should work too (i.e. https://bitbucket.company-server.url/users/username/repos/my-repo/pull-requests/1).

Relevant sections of code:

• pr-agent/pr_agent/git_providers/bitbucket_server_provider.py

  Lines 329 to 336 in aef9a04

  	def _parse_bitbucket_server(url: str) -> str:
  	# pr url format: f"{bitbucket_server}/projects/{project_name}/repos/{repository_name}/pull-requests/{pr_id}"
  	parsed_url = urlparse(url)
  	server_path = parsed_url.path.split("/projects/")
  	if len(server_path) > 1:
  	server_path = server_path[0].strip("/")
  	return f"{parsed_url.scheme}://{parsed_url.netloc}/{server_path}".strip("/")
  	return f"{parsed_url.scheme}://{parsed_url.netloc}"

We are open to pull-request from the community to address this, which would add support for 'personal spaces', and also retain the current support
