https://docs.github.com/en/rest/pages/pages?apiVersion=2022-11-28#create-a-github-pages-site--parameters

build_type string
The process in which the Page will be built. Possible values are "legacy" and "workflow".

Can be one of: legacy, workflow

Right now only 'legacy' variant is supported: https://github.com/mineiros-io/terraform-github-repository/blob/main/README.md#var-pages

This module sets the minimum required version of the GitHub provider to v4.20+.

The build_type argument to github_repository resource was added in v5.26.0 of the terraform-provider-github via integrations/terraform-provider-github#1663. Since the argument sets legacy as the default value, it currently works with this module for the newer versions of the provider.

If the argument needs to be supported, this module would need to up the minimum required version for the provider and also write extra code to support the various combinations of the build_type and source arguments.
