After upgrading from 12.9.2 to 12.10.0 can't run pipelines on protected branch.

If branch fully protected (no one have right to push or merge) we can't run pipelines manually and via API. When we triggering pipeline we are receiving error "Insufficient permissions for protected ref 'master'"

Steps to reproduce

Protect branch with no one has right and try to run pipeline.

Example Project

https://gitlab.com/boris.efron1/sample-alpine-build/pipelines
