Incorrect Import Path in VulnTotal Github datasource #1499

There is an incorrect import path in the vulntotal/datasources/github.py file. The current import statement:

from fetchcode.package_versions import github_response

should be updated to:

from fetchcode.utils import github_response

Steps to Reproduce:

• Attempt to run the code in vulntotal/datasources/github.py.
• Observe the import error indicating that github_response cannot be found in fetchcode.package_versions.

Expected Behavior:

• The import should work correctly, and the github_response function should be imported from fetchcode.utils.

Additional Context:

• This change is necessary to align with the current structure of the fetchcode package.
