Node.js: Fix linting doc snippets

[helderco]

Fixes #4857

I removed the duplication in eslint and prettier configs by extending them, same as I did in Python.

So you can lint docs from sdk/nodejs directory:

yarn docs:lint

And format:

yarn docs:fmt

The failing rust actions should be fixed in:

• Fix Rust SDK errors #5380

Nice improvements!

Is it OK to leave this as is? cc @slumbering

> yarn docs:lint
yarn run v1.22.19
$ yarn eslint --max-warnings=0 --resolve-plugins-relative-to=./ ../../docs/current

✨  Done in 3.18s.

Same issue is happening even after rebasing on top of main.

@gerhard Yeah, we should upgrade that but I'd say it's a different PR. Not introduced by this one.

[helderco]

This would be a downgrade actually. Probably @typescript-eslint/typescript-estree is too strict on typescript <5.1.0 here. It's working fine, on a next update they'll probably bump that upper limit and the warning will go away.

For reference this was only closed 3 days ago:

• TypeScript 5.1 Support typescript-eslint/typescript-eslint#6934

[gerhard]

Sounds good to me!
