can you re-add the docs? I have users of this repo that aren't going to decipher the code

[tplass-ias]

you also reverted my test, so it is not clear in the new code state even from the example code executions in the repo that this env var is supported 😭

[alexef]

@tplass-ias sure thing, will do: #247

[tplass-ias]

also, does this now require the token to exist in the config file again? I don't want to share a file with a github token, I do want to share a file with the execution state of auto-pr

[tplass-ias]

yeah actually, @alexef please fully restore, the env var needs to be supported in run(), not just init() like the other person pointed out. By reverting this PR, you are forcing me to store the token in db.json again, which is exactly what I want to avoid
