Types don't load if alias in import map isn't exact match of package name when importing currency.js from npm

[Benjiko99]

Version: Deno 1.44.0; VS Code Extension v3.37.1

VS Code doesn't show types for a package (tried npm and esh.sh) defined in import maps, if the alias doesn't exactly match the name of the package.

Aliasing npm:currency.js as currency.js will correctly display types in the IDE:
"imports": { "currency.js": "npm:currency.js@2.0.4" }}

If using any other alias, e.g. currency, currency_js, etc. the IDE will stop showing types for the package.

The code compiles and runs in all cases, only type information is affected.

This is a design limitation with TypeScript because the package currency.js incorrectly defines its types using a global ambient module:

declare module 'currency.js' {
...
}

The fix here would be for currency.js to not use one of these and stop saying it's only available at "currency.js".
