[BUG] NPM package has types (*.d.ts) in incorrect location

[BobbyL2k]

Software versions

BokehJS version: broken since 3.1.0 to current version 3.4.1

Browser name and version

Jupyter notebook / Jupyter Lab version

Expected behavior

Import Bokeh in TypeScript should work when installing

npm install @bokeh/bokehjs

import * as Bokeh from '@bokeh/bokehjs';

TypeScript should not complain about type information being missing.

node_modules/@bokeh/bokehjs/package.json expect types information under build/js/types (see

bokeh/bokehjs/package.json

Line 41 in cf19b57

"types": "build/js/types/bokeh.d.ts",

)

However the pre-compiled files under build/js do not match this layout.
Types are located under build/js/lib instead of build/js/types.

This is easily verifiable by going to NPM package registry and see how there is no types directory

https://www.npmjs.com/package/@bokeh/bokehjs?activeTab=code

Observed behavior

Could not find a declaration file for module '@bokeh/bokehjs'. '/path/to/project/node_modules/@bokeh/bokehjs/build/js/lib/bokeh.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/bokeh__bokehjs` if it exists or add a new declaration (.d.ts) file containing `declare module '@bokeh/bokehjs';`
```

### Example code

```typescript
import * as Bokeh from '@bokeh/bokehjs';
```
