quality(apidocs): remove warnings from build scripts (#94729)

while working api docs, i've noticed two new warnings are occuring due
to new node / pnpm stuff.

This PR addresses two:

1. we add a `api-docs/pnpm-workspace.yaml` that gets rid of this error:
```
│   Ignored build scripts: es5-ext.                                                          │
│   Run "pnpm approve-builds" to pick which dependencies should be allowed to run scripts.
```
2. we add `"type":"module"` in the package json to remove 
```
(node:5599) [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file:///Users/jferge/code/sentry/api-docs/index.ts is not specified and it doesn't parse as CommonJS.
Reparsing as ES module because module syntax was detected. This incurs a performance overhead.
To eliminate this warning, add "type": "module" to /Users/jferge/code/sentry/api-docs/package.json.
```
