docs: update Ubuntu installation instructions

- The ubuntu-wine ppa is deprecated, see
  https://launchpad.net/~ubuntu-wine/+archive/ubuntu/ppa.
  But wine is available from the Ubuntu archives anyway.  Not
  sure if the winehq packages should be referenced here.
- Use "apt" instead of "apt-get".  For non-scripted
  commands this is recommended nowadays.  The command exists
  for multiple years now.
- Update package installation list according to the updated
  debian/control.
