ci: drop root packageManager field to unblock yarn link in tests

Yarn 1.22.22 (the system yarn on GitHub runners) refuses to run when
it finds a `packageManager` value that doesn't start with `yarn@`. The
CLI init tests and the basic-event-handlers example both shell out to
yarn (`yarn link @graphprotocol/graph-cli`, `yarn codegen`) from
directories nested inside the repo, so yarn walks up to the root and
bails on `pnpm@10.17.1`.

Drop the field; tighten `engines.pnpm` to `^10`; pin the pnpm version
in CI by passing `packageManagerVersion: '10.17.1'` to the setup-node
composite action. While there, fix the shell in the action so the
input is actually honored (the previous `if [ ! -z {{inputs.packageManager}} ]`
was a literal-string test and never reflected the input value).
