[FIX] package.json: Downgrade pacote from 11.1.4 to 9.5.12

There has been a lot of development in pacote since v9:
npm/pacote@v9...latest

It seems that some things don't work as expected with the newer
releases, maybe because of newer transitive dependencies.

For once I got "invalid json response body" errors while fetching from
an internal registry. Then there's also #298. This change resolves both
issues (and possibly more we don't know of yet).

Resolves #298
