build(ci): fix patch set generation to handle modern react-native / yarn

[mikehardy]

Description

react-native 0.74+ tries to init a git repository which doesn't work well for us in CI
react-native 0.74+ uses yarn3+ by default which has 3 problems with our usage:

• it needs --dev not --save-dev to install a devDependency
• you have to turn off immutability (on by default in CI) for it to init a project like we do
• it does not handle executable bits correctly of our ios_config.sh scripts during the pack of our modules
