Show JsDoc documentation in auto-completion hints

[Xkonti]

I believe this was implemented at some point. Displaying JsDoc comments would drastically improve the auto-completion or docs-on-hover usability. Many vals and external libraries utilize JsDocs to provide some in-line documentation. For example on the screenshotbelow there are no docs displayed other than the typescript-derived function definition:

This function has a JsDoc providing more info on how to use it:

/**
 * Get many key-value pairs from the cache that match the given prefix.
 * @param prefix The prefix to match keys against. If not provided, all keys are considered.
 * @param limit The maximum number of key-value pairs to return. If 0, no limit is applied.
 * @returns An array of key-value pairs. Each pair is an object with 'key' and 'value' properties.
 */
export async function getMany<T = unknown>(
  prefix: string | undefined = undefined,
  limit: number = 0,
): Promise<Array<{ key: string; value: T }>> {
...
}

Interesting! I think it's implemented for default TypeScript types:

But we should also implement it on imported vals. And/or we could pull in the val's readme...
