Pull request overview

This PR makes the --target-uploads-url command-line option visible in help output by removing the IsHidden = true property. Previously, this option was hidden from users running --help, making it difficult to discover and use when migrating to non-github.com targets.

Changes:

• Removed IsHidden = true from the TargetUploadsUrl option across multiple command classes
• Simplified the option initialization by removing the object initializer block

Since this PR was created new commands have been added here like gl2gh which also takes the --target-uploads-url and is also hidden from --help.

These changes will likely have to be re-applied elsewhere.
