Issue description

toggldesktop fails to build.

Steps to reproduce

https://hydra.nixos.org/job/nixpkgs/trunk/toggldesktop.x86_64-linux

Technical details

The build error is in an internal dependency, qt-oauth-lib. The nix derivation uses the upstream version from Github but Toggl is actually using a vendored internal version that has a number of fixes in it. The build error is due to using the discontinued QtWebKit library. Toggl's internal version uses QtWebEngine. This problem has been noted in #53079.
