Switch from "master" to "main" breaks update script

[PieterBoeren]

The recent switch from "master" to "main", breaks the update script (satellite-update):

Your configuration specifies to merge with the ref 'refs/heads/master' from the remote, but no such ref was fetched.

I manually fixed it by navigating to /usr/local/src/companion-satellite and do a git checkout main and re-run the script. This probably should be documented somewhere...

This can be fixed by running the line:

sudo sh -c "cd /usr/local/src/companion-satellite && git fetch --all && git reset --hard && git checkout main"

Or you can flash the latest image instead, this also means the os will get an update to the latest release.

I don't think it is a good idea to rename the branch back now, so hopefully this command will be sufficient.
