Easy add + generate: bundle init rails new blog for fast bootstrapping ✨

[emilebosch]

So just a quick interesting idea. Oftentimes you want to bootstrap a project quickly. It would be nice if that was possible in such a way, that you both can create the bundler file, add the gem, and run a command with its primary executable of said gem.
A super fast way to init a project and start, basically simplifies a couple of commands:

bundle init rails new blog

Becomes

bundle init
bundle add rails
bundle exec rails <whatever the user types>

Would work for the projects where the name is the same as the primary executable.

Hello! Feel free to check recently added gem exec command. Ensure you're running latest rubygems (gem update --system) and type gem exec --help. You can find more info at https://github.com/rubygems/rfcs/blob/master/text/0008-gem-exec.md.

Hi @simi! So fun hahah! i've proposed the gem exec back in 2019 in #2872. The reason i never continued is because i didnt feel 'right' .

Closing since gem exec is now a thing.
