Hugo Locurcio 411d9247be GitHub Actions: Use the new way to toggle Bundler's deployment mode
This silences the following warning message:

[DEPRECATED] The `--deployment` flag is deprecated because it relies
on being remembered across bundler invocations, which bundler will
no longer do in future versions. Instead please use
`bundle config set --local deployment 'true'`, and stop using this flag
