[BUG] Readme contradicts docs on recommended Unity version

[andybak]

Docs: 2022.3.62f1
Readme: 2022.3.39f1

(It should probably actually be 2022.3.62f2 in both cases as this is the current approved version that fixes last week's critical CVE)

Good point! We're actually up to 6000.2.6f2 now! So both are out of date. We are about to unleash a huge update which will hopefully unify and consolidate the docs finally.

I'm actually about to tackle the docs right now, any input you have on what's important would be much appreciated!
