lsp: Cannot find typescript definition for jsr:@ts-morph/bootstrap

[jeiea]

Steps to reproduce

1. Environment: macOS Sequoia 15.4, Deno 2.2.6
2. Create the following source.

import { createProject } from "jsr:@ts-morph/bootstrap";

const project = await createProject();
const file = project.createSourceFile("index.ts");
file;

3. Type . right after file.

Expected behavior

Autocomplete should work.

Actual behavior

Doesn't work.

Additional context

When I replace jsr: with npm:, autocomplete works.

Seems to only affect the LSP.
