community/calamares-extensions: change min pass length
Require at least 6 characters instead of 8 and mention that digits can
also be used. Most users set something like a 6 digit number on their
lockscreen, it is even what we have by default in the postmarketOS
images when you don't use the installer. So requiring 8 in the installer
does not make sense.
Upstream: https://github.com/calamares/calamares-extensions/pull/24
Why add this patch now?
- Preparing the v23.06 postmarketOS release
- We put our patches through (pmOS, alpine) edge first, before backporting to stable
- This package is in alpine so I put it here
- I did ask calamares-extensions upstream to tag a new release, but probably will take a bit.
If Alpine would rather not have me add this, that's also fine then I'll put it in pmaports master until there is a new release of calamares-extensions.
