Include additional docs upload format "xml_tar" (#79) In the ongoing work to consolidate the rendered docs for all graph repositories (`cugraph`, `cugraph-ops`, `wholegraph`) into one place, `wholegraph` and `cugraph-ops` c++ docs will be uploaded as xml tarballs, which will then be consumed during the docs build process for `cugraph` and ultimately rendered under `cugraph`. This PR enables the tarball upload.
