ci(enable lockfile) bump pnpm and node for development

[birkskyum]

This updates the pnpm version to one compatible with the existing lockfile, and hte same as solid-start uses (faster ci, because it can install from lockfile)
This updates node to v22 in ci, which is the current LTS

we need this for reproduction of builds
Without this PR each CI release is made without a lockfile, making ti impossible for us to go back in time and make a build of say version 1.9.4 exactly like it was at the time of release, because we don't have proper information about which nested deps versions were used. This makes e.g. debugging of #2436 a lot harder, because a local build at that commit isn't behaving like the published 1.9.4 distribution.

(this is also a problem on the next branch, where similar changes should be applied)
