Update pnpm to v9

I ended up updating pnpm to v9, so I'm leaving this as a suggestion for everyone to bump their versions as well.

PS: I didn't experience any breaking changes, but thought it would be better to have a separate PR for this anyway

PS: lint check failed on github actions, so I had to update biome and it introduced a few breaking changes 😬

Ok, this actually triggered a few extra changes 🤦‍♂️
GitHub lint check failed - for some reason this update made it use biome 1.8 instead of 1.5 which was the one we were using (couldn't figure out why 🤔)
Anyway, I decided to bump all dependencies to their latest versions. There were no major updates, so we should be ok.
Even though biome updated a minor version, there were a few breaking changes to their config file 🤷‍♂️
I fixed everything and it should be straightforward to update on your end.
Ps: my vscode got a bit lost during these changes and apparently deleting node_modules (using rimraf) and reinstalling them did the trick - so keep that in mind if your auto-save breaks for some reason 😬
Ps2: why version updates have to be so painful at times?! 🙄
