Master vs dev discrepancy

[inventor96]

While troubleshooting openaps/oref0#1471, noticed that the instructions provide a link to the intall script from the master branch, but run it passing dev as the branch to use. See https://github.com/openaps/docs/blob/master/docs/docs/Build%20Your%20Rig/pi-install.md?plain=1#L63. It looks like this was changed in #1547, but the discrepancy breaks the install because of the python-pip package not being available.

The dev version of the install script does not contain a reference to the package (it was moved to the openaps-packages.sh file, so we need to either change the install script URL to reference the dev branch as well:

curl -s https://raw.githubusercontent.com/openaps/oref0/dev/bin/openaps-install.sh > /tmp/openaps-install.sh && bash /tmp/openaps-install.sh dev

Or merge the current dev branch to master and remove the dev argument to the script:

curl -s https://raw.githubusercontent.com/openaps/oref0/master/bin/openaps-install.sh > /tmp/openaps-install.sh && bash /tmp/openaps-install.sh
