wireless-regdb: Update regulatory rules for Ukraine (UA) on 6GHz

Hi,

6GHz wireless band was recently allowed by Ukraine government for WiFi 
6e standard indoor use.

Could you please add the appropriate setting to wireless-regdb

I'm not familiar with wireless-regdb format nor an expert on wireless 
technology to create PR myself
