* Remove obsolete slapslay.phrases.txt
That plugin isn't in the stock arsenal since forever.
* Remove "Dead Player Rename" phrase
Unused since #313
* Remove nominations phrases from rockthevote
Those phrases were moved to their own nominations.phrases.txt
* Remove "Next Map" phrase from nextmap.phrases.txt
It was moved to basetriggers.phrases.txt
* Remove unused phrases from common.phrases.txt
Only "Slapped Player" was moved to funvotes.phrases.txt
* Delete empty phrase files
* Fix workflow python version selection
3.10 would select Python 3.1 and fail
* Deduplicate "Please select a map" phrase
Only keep it in the plugin.basecommands.txt file and remove it from the basevotes.phrases.txt.
Both plugins using the phrase load the basecommands phrases.
* Allow manual triggering of translations action
* Actually use the nextmap phrases
They were never referenced in the plugin. The "ago" phrase doesn't work the way it is and needs more rethinking.
