@typescript/ata should support `npm:` specifiers

Keywords: Automatic Type Acquisition, npm

I would like to produce a TypeScript playground using a particular version of a package. The suggestion is to support npm: package specifiers in import, like Deno does.

import { IInstruction, address } from 'npm:@solana/web3.js@2';

// @ts-expect-error
const ix: IInstruction = {
    keys: [],
    programAddress: address('abc'),
}

Output

import { address } from 'npm:@solana/web3.js@2';
// @ts-expect-error
const ix = {
    keys: [],
    programAddress: address('abc'),
};
