Windows support running `hanami dev`

Tried to start developing on a windows machine and running into the following error executing: `bundle exec hanami dev`:

`C:/Ruby33-x64/lib/ruby/3.3.0/open3.rb:534:in `spawn': Exec format error - bin/dev (Errno::ENOEXEC)`

It look's like this might have been a bug introduced relatively recently? Or at least reported recently: https://www.reddit.com/r/ruby/comments/1b1c0yp/hanami_21_is_out/

### Reproducible Steps

Create a new Hanami app on a windows machine and run the command:
`gem install hanami`
`hanami new win_app`
`cd win_app`
`bundle exec hanami dev`

It seems like it comes down to windows just not natively supporting bash? Although, even using Git Bash - same issue.

A few things I tried:
1) Running `hanami server` directly seems to start everything up - but probably don't want to circumvent the procfile
2) Converting `dev.sh` to `dev.bat` _half_ works - the asset command forks a process, where forking isn't supported on non-POSIX (https://ruby-doc.org/core-2.6.2/Process.html#method-c-fork)

Any thoughts on Windows support?
