Summary of changes
Changes introduced in this pull request:

• added a workflow running every hour.
• Downloads filecoin built-in actors released in the last two years
• Checks if we need to do any mirroring by comparing downloaded actors byte for byte with the ones in the object storage(R2 and DO)
• If yes, upload the missing assets.

Reference issue to close (if applicable)

Closes #323

Mirroring only the latest release is not useful. The goal is to mirror all releases, properly versioned. The end structure of the mirror should be like (though more complete):

├── v10.0.0
│   ├── builtin-actors-devnet.car
│   └── builtin-actors-mainnet.car
├── v10.0.0-rc.1
│   └── builtin-actors-calibrationnet.car
├── v11.0.0
│   ├── builtin-actors-devnet.car
│   └── builtin-actors-mainnet.car

Looks good, however since we're running this via cron - why don't we also make sure that dependencies are cahched? Here's a guide.

How about caching the installation itself: https://github.com/snok/install-poetry?tab=readme-ov-file#caching-the-poetry-installation

There are also useful guides on how to cache deps in the above readme too.

@samuelarogbonlo I appreciate the effort of making it enterprise-grade, but a simple lambda would do enough for having a configurable sink. We're getting into non-trivial Python code where we shouldn't.

Pseudocode of what I mean:

sink = if use_local
  || save_to_file(file)
else
  || save_to_s3(file)
end

You also added quite a bit of unused methods. Let's keep things as simple as possible.

I think there is exactly one unused method: exists. What you suggest would work, if we didn't need list_files that has quite a bit of logic. And just like that one lambda is not sufficient anymore, unless we want to duplicate the logic the two sinks otherwise share.

If you guys are okay with that, then I won't block it.

@LesnyRumcajs. Good?

I kinda get where you are coming from, but I don't see a better way here. This is not too advanced, just using some OOP that happens to be quite ugly in Python :)
