docs(wasm-languages): go updates

[vdice]

This PR originally started with the goal of updating the example manifest to v2 and removing the base trigger config due to be removed in Spin 3 (ref #1376 (comment)).

I coudn't help but update a few tangential items along the way, but stopped short of revising the go/tinygo lay-of-the-land.

We can either collaborate in this PR to update the main text to reflect recent go/tinygo updates/support (pinging @adamreese @rajatjindal and others) or this can be a follow-up.

Excellent, thanks!

@vdice The changes in this PR look good. Is there a particular section that you were looking for more input on?

[vdice]

@adamreese Yes mostly to see if anything should to be updated/revised in the first overview section of the page, i.e.

developer/content/wasm-languages/go-lang.md

Lines 12 to 43 in 446c94a

	Go was early to the WebAssembly game, with the Go compiler producing `wasm32` output alongside its regularly supported build targets.
	But the core Go tools have fallen behind.
	Instead, the alterative Go implementation called [TinyGo](https://tinygo.org/) seems to have taken the lead.
	## Available Implementations
	- Go supports browser-based WebAssembly
	- TinyGo supports `wasm32-wasi` as a build target
	- The [Elements compiler](https://www.elementscompiler.com/elements/) may also support compiling browser-oriented Wasm
	We have had the best luck with TinyGo.
	## Usage
	With TinyGo, it is possible to compile _most_ Go code into Wasm with WASI support.
	That means you can write Go code targeting the Fermyon Platform.
	## Pros and Cons
	Things we like:
	- TinyGo works very well
	- Spin has full support for Go
	We're neutral about:
	- The resulting binary sizes start at around 300k, but can rapidly climb
	Things we're not big fans of:
	- Upstream (mainline) Go does not have WASI support
	- TinyGo is still missing (mostly reflection-based) features of Go

Build error is unrelated broken links which are fixed in the v3 work.
