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

[ronaldsteen]

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, 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.
