Multi arch support

[erudisch]

Description:
Hi

We are using your action in our project for a multi arch build - amd64 and arm64. Sadly your action only supports caching for amd64. Are there any plans to add an aditional cache for other architecures?

Referenced Issue:

• can't support multi-arch go environment #166

Justification:
Used in a high frequent multi arch docker build.

Are you willing to submit a PR?
Yes. I could implement this feature. A little introduction and guidance for where to look would be much appreciated.

Best
Erik
