Thought for a moment

Fixed the BQ25622RYKR symbol metadata to match the TI datasheet.
Changes made:
  • Renamed PMID_GD → PG
  • Renamed ILIM/D- → ILIM
  • Renamed TS_BIAS/D+ → TS_BIAS
  • Added datasheet-based pin descriptions for all 18 pins
  • Updated pin types using standard Flux values, including open-drain outputs as Open Collector, I²C SDA as Bi-Directional, and power pins as Power In / Power Out
I verified the final symbol: all 18 pin numbers, names, descriptions, and pin types are now aligned with the TI BQ25622 pin table.
