While using the package v53.2.0 I was trying to fetch [SBOM for a repository](https://docs.github.com/en/rest/dependency-graph/sboms?apiVersion=2022-11-28#export-a-software-bill-of-materials-sbom-for-a-repository). But looks like that method is not yet implemented. Please let me know if this is a valid feature request. If it is, I would love to open a PR.
