feat(FR-1922): missing vallidation of importing from github and gitlab

[agatha197]

Resolves #5060 (FR-1922)

Improved URL validation for GitHub and GitLab repository imports

This PR enhances the validation of GitHub and GitLab repository URLs during import by:

1. Implementing more precise regex patterns that validate specific URL formats:
   • For GitHub: Allows https://github.com/owner/repo, https://github.com/owner/repo/, or https://github.com/owner/repo/tree/branch
   • For GitLab: Allows https://gitlab.com/owner/repo, https://gitlab.com/owner/repo/, or https://gitlab.com/owner/repo/-/tree/branch
2. Extracting the regex patterns into named constants (GITHUB_URL_REGEX and GITLAB_URL_REGEX) for better code organization and reusability

Checklist:

• Documentation
• Minium required manager version
• Specific setting for review (eg., KB link, endpoint or how to setup)
• Minimum requirements to check during review
• Test case(s) to demonstrate the difference of before/after
