Update darwin patcher for 3.270.1 (Steam) (#714)

## Scope

I've created a new patch_definitions with offsets and patches for a
newer version of the game

## Test Plan

Run the patcher and start the game, check that requests go through

## Checklist

<!--
Once you create the PR, the checklist will be added below this comment
automatically (based on what files you've changed).
It's just a few reminders to make sure everything is perfect. You can
place an "X" in the boxes to tick them off.
When you have completed the checklist, press the "Ready for review"
button.

--------
#### General
- [x] I've run Prettier to format any changed files
- [x] I've verified that my changes work, and included a test plan
