chore(ci): widen check-fmt trigger to run on prettier-eligible file changes

Add a prettier path filter in changes.yml that matches *.yml, *.yaml,
*.js, *.ts, *.tsx, *.json, and prettier config files. Use it as an
additional trigger for check-fmt so PRs touching only workflows, config
examples, or website JS/JSON also get format-checked.
