docs(kong.conf): add section for wasm nginx.conf directives

[flrgh]

It's pretty wordy because there's a lot to explain. I'm also not sure what it will look like when rendered for docs.konghq.com, so if anyone has pointers on how to preview the end result, let me know.

Not sure if this needs a backport to release/3.4.x 🤔. @Guaris, can you tell me if we specifically/exclusively build auto-generated docs from release branches in Kong/kong? In other words, do I need to backport this to release/3.4.x in order for it to one day show up in https://docs.konghq.com/gateway/3.4.x/?

This commit 550ef15 says that the autodocs scripts that used to generate Markdown from this were replaced by a script in Enterprise which builds both EE and OSS docs, so there should be a script somewhere that allows building a previewable Markdown... 🤔

Just gave it a quick skim, but will get back to it more carefully tomorrow!

Labeling this one for backport for consistency's sake. It's a doc-only change, so it's harmless and doesn't necessitate a new release. If that's not desired, feel free to remove the label.

Thanks.

You don't need to backport this as far as I know. The process runs on the checkedout branch when you run the script.

@locao could I get a +1 on this?
