ci: forward bump input from workflow_dispatch to reusable release workflow

The caller workflow defined workflow_dispatch without inputs, so
'gh workflow run release.yml --field bump=...' failed with
'Unexpected inputs provided: ["bump"]'. Declare the bump input on
the caller and forward it via 'with:' to the reusable workflow.

Tag push still works unchanged — inputs.bump is empty, which the
reusable workflow's bump job treats as a no-op.
