Subject: [PATCH] build(docs-infra): ensure root node_modules exists (#25811)

Now that the doc-gen parses the imports of TS source
files we need to ensure that the root node_modules
exists. Otherwise running `yarn docs` produces an
obscure error:

```
Error: No SourceFile found with path node_modules/@types/jasmine/index.d.ts
```

Closes #25759

PR Close #25811
