fix(ci): remove an input the reusable deploy workflow does not accept (#126)

The .nvmrc change rewrote every 'node-version:' in .github/workflows,
including the one in this shim — but that line was an INPUT to the shared
deploy workflow, not a setup-node arg. An undeclared input makes the
workflow invalid, and GitHub reports startup_failure: a deploy that never
ran, rendered as a red X with no logs.

The shared workflow reads .nvmrc itself now, so the shim needs nothing.
