[JavaScript] Feature Request: Support Node.js v18

[MH4GF]

Hi, maintainers.

We are building a tool to parse database schemas and automatically generate ER diagrams, and we are using Prism to parse schema.rb in Ruby on Rails.
https://github.com/liam-hq/liam/tree/main/frontend/packages/db-structure/src/parser/schemarb

I call prism in the Node.js CLI, but Node.js v18 does not have wasi.getImportObject(), so I get an error.

(node:1048) ExperimentalWarning: WASI is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
file:///Users/mh4gf/ghq/github.com/MH4GF/debug-prism-js/node_modules/@ruby/prism/src/index.js:20
  const instance = await WebAssembly.instantiate(wasm, wasi.getImportObject());
                                                            ^

TypeError: wasi.getImportObject is not a function

Node.js v18.20.5

End of Life for Node.js v18.x is April 2025, but it makes sense to support v18 until then.
https://github.com/nodejs/release#release-schedule

I think this line could be rewritten as follows, what do you think?

prism/javascript/src/index.js

Line 20 in cdf702b

const instance = await WebAssembly.instantiate(wasm, wasi.getImportObject());

  const instance = await WebAssembly.instantiate(wasm, { wasi_snapshot_preview1: wasi.wasiImport });

Thank you!!

Sorry I didn't see this. Since we're past April 2025 I'm going to close.
