@actions/cache package version no longer works

[McTalian]

GitHub has deprecated older versions of @actions/cache. The lowest working version for v3 is 3.4.0 and the project is currently on 3.3.0

I'll take a look at putting up a PR tomorrow morning! Should be pretty quick.

Turns out actions/toolkit repo didn't publish a 3.4.x version, so it has to be ^4.0.0

PR incoming

EDIT: someone already got it 😄

All dependencies have been updated, use v13 or newer
