mac-latest runners no longer provision enough disk space

Description

Previously the mac-latest runners would have enough disk space to install a single version of the Unity Editor to build my games with, but now that is no longer the case.

Is it regression?

yes

Expected behavior

Enough disk space to install the required software for the Unity Engine and download and build my game.

Previous version of the runner had enough space. Prev good run: https://github.com/buildalon/unity-setup/actions/runs/10542831903

Actual behavior

Running out of disk space, when previously there was enough.
