Update pnpm in the project

The current pnpm version is not supported by the project, which may cause some conflicts/confusion.
The package.json will have to be updated in order to support the new version. Also see if all libraries (that are being used) are supported in the new version, and if the dashboard won't break.

Start with package.json, which is the only file named in the issue, and identify the required pnpm version and the libraries it declares. Check whether those libraries and the dashboard remain compatible after the update; done means the package metadata supports the new pnpm version without dashboard breakage.
