feat: support go provided.al2 runtime

[Skn0tt]

🎉 Thanks for submitting a pull request! 🎉

Summary

AWS will deprecate the go1.x runtime by end of year, asking customers to deploy to provided.al2 going forward. It requires ZIPs to contain a single file called bootstrap, similar to Rust. This PR adds a featureflag to ZISI that makes that switch, and writes the result of it into manifest.json so we can detect this during deployment.

What will we do with this property?

[Skn0tt]

We'll read it in open-api, so we can propagate it through nf-server into BitBalloon and functions-origin. They can then read it and use provided.al2 as the AWS runtime, if it's present. If you have an idea for a solution where we don't need to propagate this so far, i'd be happy to hear it!

[eduardoboucas]

Could we use the existing runtimeVersion property for that?

zip-it-and-ship-it/src/manifest.ts

Line 16 in 626d63d

runtimeVersion?: string

[Skn0tt]

I guess so, but that'd still require changes to all three services. But that field is probably better-suited. I'll make that update!

[Skn0tt]

done in 80a3c66

[eduardoboucas]

Just for consistency with what we do in Node.js, it might be nice to always return the runtime version, even if it's the old one.

Not a big deal, though.

Suggested change

	runtimeVersion: featureFlags.zisi_golang_use_al2 ? 'provided.al2' : undefined,
	runtimeVersion: featureFlags.zisi_golang_use_al2 ? 'provided.al2' : 'go1.x',

[Skn0tt]

Thought about that as well, but I didn't want to introduce changes when the flag is off. undefined should do that.
