Azure doesn't accept `Transfer-Encoding: chunked` on their token endpoint, but with the switch to ureq we always send requests with this set.
Fix by switching to `Content-Length` in the header instead. ureq only sets `Transfer-Encoding: chunked` when the body length is not known beforehand, which is the case when using `send`. See https://docs.rs/ureq/2.4.0/ureq/index.html#content-length-and-transfer-encoding See https://forum.proxmox.com/threads/openid-401-with-azure-ad.105892/ for the issue.
