On GitHub Enterprise Server, catalog and scaffold only support the latest version, not specific versions

[brant4test]

Describe the bug

When using a repo on GitHub Enterprise Server, the end-to-end process of using Terragrunt Catalog and Scaffold only works with the latest version and does not support specifying a version.

Steps To Reproduce

Steps to reproduce the behavior:

1. Use a repo on GitHub Enterprise Server.
2. Try specifying a version using //.?ref=v6.1.0 or ?ref=v6.1.0.
3. Run the terragrunt catalog command.
4. Observe that no code is scaffolded and the directory remains empty.

22:57:39.954 WARN   Using `terragrunt.hcl` as the root of Terragrunt configurations is an anti-pattern, and no longer recommended. In a future version of Terragrunt, this will result in an error. You are advised to use a differently named file like `root.hcl` instead. For more information, see https://terragrunt.gruntwork.io/docs/migrate/migrating-from-root-terragrunt-hcl

Expected behavior

The scaffolding process should work correctly when specifying a version, and code should be scaffolded into the directory.

Nice to haves

The terminal output is already included in the Steps To Reproduce section.
