deprecate: mark has_downloads variable as deprecated (#17)

* deprecate: mark has_downloads variable as deprecated

The `has_downloads` attribute is officially deprecated in the GitHub
provider (v6.10.2) and will be removed in a future version. This change:

- Adds deprecation notice to variable description
- Removes has_downloads from github_repository resource
- Adds check block to warn users who set has_downloads=true
- Bumps minimum Terraform version to 1.5 (required for check blocks)

The variable is retained for backward compatibility so existing
configurations won't break, but users will see a warning.

* docs: update README with Terraform 1.5 requirement and deprecation notice

Auto-generated documentation updates reflecting:
- Minimum Terraform version changed to >= 1.5
- has_downloads variable marked as deprecated

* fix: remove unused has_downloads variable from examples

The deprecated has_downloads variable was declared in both example
files but not used, causing tflint to fail CI with "variable is
declared but not used" warnings.

* fix: remove has_downloads from fixtures file

The terratest was failing because the fixtures file still referenced
the has_downloads variable which was removed from the example.

* fix: remove has_downloads assertion from test

The has_downloads field is deprecated by GitHub and was removed from
the module. The test assertion needs to be removed as well.
