feat: upload go binaries as al2-compatible zip

[Skn0tt]

Ensures that Go binaries that have provided.al2 as their runtimeVersion are uploaded in a provided.al2-compatible ZIP. This means that the name of the binary inside the created ZIP needs to be bootstrap, and that we're sending runtime=provided.al2 to the Netlify API.

how are we making sure that binaries we get are ready for this runtime? they need to use a certain version of the Lambda Go SDK right?

[Skn0tt]

The binary needs to be built with GOOS=linux GOARCH=amd64: https://docs.aws.amazon.com/lambda/latest/dg/golang-package.html#heading:r1i:
This hasn't changed between the go1.x and provided.al2 runtimes, so our customers won't need to change anything to the binaries they're uploading.

hmm, i was under the impression that you needed to run a minimum version of the Go SDK for the provided runtime to be supported, but i can't find any docs on this. i guess that must have been possible for a long time.
still the risk that some people have very old go modules that they use for building their Go functions, not sure

[Skn0tt]

If there's no manifest file, there's no change. We're still uploading stuff as go, for now.

[Skn0tt]

If there's a runtimeVersion: "provided.al2" in the manifest, we now pick that up and send it to the API as the runtime.

I've made some updates to go along with netlify/zip-it-and-ship-it#1609, and would love another review.

Uh-oh, the tests are failing on windows, probably because

open-api/go/porcelain/deploy.go

Lines 919 to 944 in b2b8227

	func goFile(filePath string, i os.FileInfo, observer DeployObserver) bool {
	warner, hasWarner := observer.(DeployWarner)
	if m := i.Mode(); m&0111 == 0 { // check if it's an executable file
	if hasWarner {
	warner.OnWalkWarning(filePath, "Go binary does not have executable permissions")
	}
	return false
	}
	if _, err := elf.Open(filePath); err != nil { // check if it's a linux executable
	if hasWarner {
	warner.OnWalkWarning(filePath, "Go binary is not a linux executable")
	}
	return false
	}
	v, err := version.ReadExe(filePath)
	if err != nil || !strings.HasPrefix(v.Release, "go1.") {
	if hasWarner {
	warner.OnWalkWarning(filePath, "Unable to detect Go version 1.x")
	}
	}
	return true
	}

isn't working correctly on windows 🫤

LGTM. CI seems to be complaining but I don't know how relevant it is since we've changed the porcelain part and nothing on the auto generated bit - https://github.com/netlify/open-api/actions/runs/6494408840/job/17671324967?pr=490#step:5:10
