Language Guide: Add (tiny)go

[kate-goldenring]

Add instructions for compiling go modules and componentizing them. For example:

tinygo build -target=wasi foo.go
wasm-tools component embed --world myworld ./foo.wit foo.wasm -o foo.embed.wasm
wasm-tools component new -o foo.component.wasm --adapt wasi_snapshot_preview1="$COMPONENT_ADAPTER" foo.embed.wasm

where the adapter is built from https://github.com/bytecodealliance/wasmtime/tree/main/crates/wasi-preview1-component-adapter
