Description of Change

Upgrade pnpm to 9.1.4 According to @Alphrag : A few things that I have seen that are good in it: it uses node-gyp v10.x which means rebuilding some dependencies won't fail (like sqlite3 if we wish at one point to upgrade it again to the latest version, but is not recommended atm), and allows shorter paths of included node-modules for windows which could fix a problem for some users
