Fix the autoInstallPeers error

[julienbrg]

In Github actions, we always get the following error:

Run pnpm install
 ERR_PNPM_LOCKFILE_CONFIG_MISMATCH  Cannot proceed with the frozen installation. The current "settings.autoInstallPeers" configuration doesn't match the value found in the lockfile

Update your lockfile using "pnpm install --no-frozen-lockfile"
Error: Process completed with exit code 1.

The checks pass when autoInstallPeers is manually set to false in the pnpm-lock.yaml file, but let's fix the Github action.
