[feature] Allow for 3rd party S3 providers

[RDeluxe]

Hi!

Opening this ticket to keep track of this potential feature : it would be great to be able to use Minio or Scaleway S3 providers with this lib.

I'm not a Golang developer, but I may give it a try in the upcoming weeks. It seems feasible.

Thanks for this action 🙏 , you may want to chime in actions/cache#354 and let them know!

Hey @RDeluxe,

Yeah, it's a good idea, I can't give you a timeframe to start working on that, though. Feel free to open a PR. :)

Hey @RDeluxe, the documentation you sent seems easy to implement.
I will try to find time to work on that in the next few days. :)
