Feature Request: Enable PROOF to Directly Use WDL and JSON Files from a GitHub Repository

[sitapriyamoorthi]

Description:
Currently, PROOF requires users to manually upload WDL and JSON files. I would like to request a feature that allows PROOF to directly access and use WDL and JSON files stored in a GitHub repository. This would improve usability by streamlining workflow setup and enabling version-controlled workflows to be easily integrated.

Proposed Feature:

• Allow users to provide a GitHub repository URL containing WDL and JSON files.
• PROOF should be able to pull the latest version of the specified files or allow users to select a specific branch/commit.
• Option to sync or update files from GitHub when changes are made.

Benefits:

• Simplifies workflow execution by eliminating manual file uploads.
• Ensures users are running the latest version of their workflows.
• Improves collaboration by allowing teams to manage workflows in GitHub.

Would love to hear thoughts on feasibility and possible implementation strategies!
