Add ability to modify Repository URL

[shreyjain1998]

For the Organization account it builds the URL like https://<org_name>@dev.azure.com/<org_name>/<repo_name>/_git/ which may not be the case always. For example, it works only if I modify the URL like https://dev.azure.com/<org_name>/<repo_name>/_git/ for me.

So, please add a functionality to modify/update the Repository base URL.
