Attempt to fix build error due to too many files open (#4198)

This PR moves the IPyWidgets renderer into its own little package so
that it has its own `node_modules` separate from the
`positron-ipywidgets` extension, then adds those `node_modules` to the
extension's `.vscodeignore` file which should stop them from being
copied over during the build.

This fixes `yarn gulp compile-extensions-build` for me locally, which
currently errors on main.
