trim language string from dialog

[niun]

Problem:

I sometimes got

CopyQ Note [2023-05-01 18:01:52.644] <Server-8336>:    Failed loading language 'deu
'

I don't really understand but the choice dialog seems to add a newline to the selected language string (only sometimes?) or isn't it removed by the split('\n') call? However, calling a trim() on language fixed the problem for me.

Thanks!
