Support globs for files to format

[tmaier]

I want to use a tool called "erb-format" to format all my *.html.erb and *.turbo_stream.erb files.

The issue is, it supports globs just poorly. One would need to run the following to format all the files:

• bin/erb-format **/*.{html,turbo_stream}.erb --write
• bin/erb-format **/**/*.{html,turbo_stream}.erb --write
• bin/erb-format **/**/**/*.{html,turbo_stream}.erb --write
• bin/erb-format **/**/**/**/*.{html,turbo_stream}.erb --write
• ...

When any of them would not find a file, it raises an error like No such file or directory @ rb_sysopen - app/**/*.turbo_stream.erb (Errno::ENOENT)

I think Dir.glob could solve this...

      files = 
        Dir.glob(@argv).map do |filename|
          [filename, File.read(filename)]
        end

In theory the double asterisk should already recurse subdirectories, maybe it's not enabled in your shell env?

For bash you should be able to enable it with shopt -s globstar, see https://askubuntu.com/a/1010708.
