comms/predict: update to 2.3.1

[upstream changes]
Release 2.3.1:
By John A. Magliacane <kd2bd@amsat.org> (05-Aug-2023):

* Fixed a bug that caused the "Upcoming Passes" list in Multi-Satellite
  tracking mode to occasionally produce erroneous results if one or
  more satellites in the database had decayed from orbit.

* The Vocalizer feature was modified to prevent it from being executed
  by a user keyboard command until after the current speech announcement
  has terminated.

* The earthtrack compilation script was modified to prevent the
  "undefined reference" errors some users experienced during the
  linking phase of the compilation process.

* All references to www.celestrak.com in the "kepupdate" script have
  been changed to celestrak.org due to the site's name change.

* Several other small coding changes were made.

----------------------------------------------------------------------------

[db changes]

- Upstream does not come with a proper build infrastructure hence
  build is done in our port Makefile now instead of copied Makefile.
- portlint and portfmt ran clearly as did poudriere.
- Added earthtrack, kepupdate and moontracker binaries
  but did not add gsat which should be a separate port IMO
