Leverage github actions cache -> runs-on s3 magic cache to reduce traffic over NAT

## Describe the Feature

Leverage github actions cache to prevent downloading Atmos binaries for each run of an action.
When github actions is used, we're able to use [RunsOn S3 cache](https://runs-on.com/caching/magic-cache/), which is fast (local in our VPC), and cheap (no traffic over our NAT gateway).

## Expected Behavior

Github Actions Cache is used.

## Use Case

We're trying to reduce the amount of traffic over our NAT gateway as much as possible. This started to add up on our AWS bill.

## Describe Ideal Solution

Local @actions/tool-cache be replace with remote GH Actions cache, or GH Actions cache being added on top of that.

## Alternatives Considered

None / couldn't think of any.
