Fix pgoapi package repository hash

[rhysd]

Short Description:

Fix 'pgoapi' package repository hash because latest one broke this bot. It seems that protobuf definition was updated. I think it is better that update pgoapi version with confirming manually.

Fixes:

• Fixed pgoapi package's commit hash to the one with which at least I confirmed this bot worked well.

The command "pip install -r requirements.txt" failed and exited with 1 during .
