Nice work on this PR! I smoke tested this PR with the go-tfe PR and things look good. I found one issue that needs to be fixed to test (see the comment), and then there are a few minor suggestions I have.

Almost there! I smoke tested with organization and workspace data sources and resources, and everything is working as expected.

Could you update the data source and resource docs for organization to include the new attribute? And then I think we're good to 🥳
