  cronjobs: various fixes and cleanup (#903)

After merging of #896 and cronjob deployment on grass.osgeo.org various issues came up which are addressed in this PR.

Important:
- fix incorrect branch in `cron_grass_new_current_build_binaries.sh`
- generate programmer's manual only in `cron_grass_new_current_build_binaries.sh`

Improvements:
- fail early rather than useless continuation (`set -e`)
- compile with 2 cores (`make -j2`)
- fix copying of `INSTALL` and `REQUIREMENTS.html` to server download directory as being renamed to `INSTALL.md` and `REQUIREMENTS.md`
- also copy `CITATION.cff` to server download directory

Misc:
- no longer generate gettext `.pot` file for transifex since we migrated to https://weblate.osgeo.org/projects/grass-gis/

(this PR potentially also addresses #814)
