feat: auto-rectify git source url

[cAmartya]

Is your feature request related to a problem? Please describe

Currently, if a user enters an extended GitHub URL instead of the repository URL.
For example, https://github.com/SwiftWave/SwiftWave/tree/main instead of https://github.com/SwiftWave/SwiftWave, then an invalid GitHub credentials alert is displayed.

Expected Changes

The input field should auto-rectify the URL by converting the provided one to the required specification.

Describe the solution you'd like

1. Trim the extra URL. URL should be of the form https://github.com/{User | Organization}/{Repository}

Describe alternatives you've considered

1. You can use regex to verify and fix the URL
2. Also make sure, the URL can be of github, gitlab or bitbucket.
