chore: fix examples workflow (#3385)

## Description

This PR fixes the `examples` workflow that attempted to use the
`gnofmt_template.yml` for running `gno fmt` on the examples folder.

The issue was that `gnofmt_template.yml` is a reusable workflow, not an
action, and the way the `fmt` job was structured in the `examples`
workflow was calling it like an action.
