[Bug][GitExtractor] GitExtractor fails with "Invalid Git URL" when using GitHub App authentication

What happened

When using GitHub App authentication to configure a GitHub connection in DevLake, the gitextractor task fails during project import with an "Invalid Git URL" error. This issue does not occur when using Personal Access Token (PAT) authentication.

• The gitextractor task fails immediately with "Invalid Git URL" error
• The CloneUrl field in _tool_github_repos is empty/null
• A malformed URL is constructed: //git:ghs_XXXXX@ (missing hostname and repository path)

What do you expect to happen

The gitextractor task should successfully clone the repository using the GitHub App credentials

How to reproduce

1. Configure a GitHub connection using GitHub App authentication (App ID + Private Key + Installation ID)
2. Successfully test the connection (connection test passes)
3. Create a project using that connection to get data on a GitHub repo.
4. Run a collection.
5. Observe that the gitextractor task fails with "Invalid Git URL" error

Github App was created with permissions described in https://devlake.apache.org/docs/Configuration/GitHub#github-apps-beta set as Read-Only.

I am using v1.0.3-beta8 docker compose.

Notice the malformed URL: url://git:ghs_XXXXXXXXXXXXXXXXXXXXXXXXXXXX@ (missing hostname and repository path)

I think that might have been due to the database already pre-populated with data from using a GitHub PAT.
I've since dropped all the tables in my DB and retriggered a fresh collection using the App only (PAT not configured anymore) and it worked ok. so there is something strange somewhere, but definitely not a p0.
