Fix double slash in GitLab and Azure DevOps web URLs

When users configure a GitLab or Azure DevOps connection with a trailing
slash in the URL (e.g., https://gitlab.example.com/), the constructed
project URLs would have a double slash (https://gitlab.example.com//path)
causing 404 errors when opening links.

This fix strips trailing slashes from the hostUrl before constructing URLs.

Fixes SOU-533
