build: update pnpm to v9 and update actions

Update pnpm to v9 and remove the "version" input from
"pnpm/action-setup" as that will now use the "packageManager" field from
`package.json`.

Add `ENABLE_EXPERIMENTAL_COREPACK=1` environment variable to the build
environment on Vercel to make sure Vercel uses corepack for the correct
version of pnpm.

Update all actions to their latest versions using hashes to prevent
tampering.
