Update Runner Helm Chart related patches applying workflow

This MR adds two changes:

1. It adds a git checkout master step before git pull for both patches command lists. This makes the base for patch applying to be most up-to-date.

2. Splits the commands list to applying and commiting the patch and separately pushing the branch. I found that each time I was copying and pasting the command without the git push step to review the commited changes before pushing them. And I think this is a very good approach and it's already done for several of our command lists. So let's do it also here.
