bash script that will pull all changes from one remote and push them to another

mirror_reposh.sh

#!/usr/bin/env bash

# the following hardcoded assumtions are made:
# - before running this script, you must locally checkout the source repo
#   - set the source remote's name in the remote variable
#   - create a target repo and add it to the local checkout with the name "mirror"
# - branch names containing "dependabot" and "renovate" are ignored
# - the repo must have a "default branch" called master, main, or develop which will be used in that order
