GHA/windows: bump Cygwin action, move package store to D:

- to benefit from the new download retry mechanism.
  https://github.com/cygwin/cygwin-install-action/pull/26

- to use a new setting that not only moves the Cygwin install target
  directory to the faster `D:` drive, but also the package download
  directory. Expecting a little performance improvement from this for
  the Cygwin install step.
