fix: add missing constructor args for OZ example contracts

The `fungible_allowlist_example` constructor requires `--name` and
`--symbol`, and `nft_enumerable_example` requires `--uri`, `--name`,
and `--symbol`. Without these, contract client generation fails with
"Missing required argument" after successful compilation and deploy.
