For #22710 - Disable run-ui in build-contributor-pr workflow

[AaronMT]

Fixes #22710

Unfortunately the problem with INSTALL_FAILED_INSUFFICIENT_STORAGE is still showcasing itself on v2.21.0 – I'm not aware of any workaround at this moment in time, so I'm disabling this step of the workflow again.
