Steps to Reproduce

2.  Do not specify the push secret explicitly in buildconfig yaml
3. The build fails to push the image with, with failure to connect to the registry

Actual results:

The secret associated with builder SA is not selected and has to be specified explicitly in buildconfig yaml for builds to succeed.

The correct push secret associated with builder SA should be selected automatically.{}

Always in OCP 4.16
