merge hefee/dev/translation-server

Originally created by @hefee on #16225 (Redmine)

Please merge the branch, but don’t stash the commits together, when merging, as they are fixing/improving things for different bugs.

• Make save-suggestions.sh cronjob more silent
• Set needed parameters for staging ikiwiki build (Improves: tails/tails#15625)
• Add an script to handle weblate merges (update-weblate_git.py)
• Refactoring update-weblate-components.py
• Use update-weblate-components.py in cron.sh (fixes tails/tails#15185)
• Use correct committer name and email for new Weblate components. (Improves: tails/sysadmin#15674)
• Create new Weblate components directly (without using ImportProject), otherwise we consume to much CPU/RAM in rescaning without need.
