feat(docs): add nodeadm wasm targets to call from docs

[ndbaker1]

Issue #, if available:

Description of changes:

It would be helpful to be able to test a NodeConfig straight from the browser without installing any tools.

This PR adds a WebAssembly package containing nodeadm's config parsing hook and provides a minimal editor that users can paste their config into.

Testing Done

deployed to my fork's ghpages: https://ndbaker1.github.io/amazon-eks-ami/nodeadm/doc/playground/

rm -rf ./site
pushd nodeadm && make wasm && popd
mkdir -p ./site/assets/javascripts && cp "$(go env GOROOT)/misc/wasm/wasm_exec.js" ./site/assets/javascripts/
mkdir -p site/assets/wasm && cp nodeadm/_bin/nodeadm.wasm ./site/assets/wasm
mkdocs gh-deploy -r ndbaker1 --dirty --no-history --force

See this guide for recommended testing for PRs. Some tests may not apply. Completing tests and providing additional validation steps are not required, but it is recommended and may reduce review time and time to merge.
