Cannot run rake test on windows.

[matiaspulmaton]

Trying to run entire test suite of rails app fails. More specifically, the Rake task test:prepare fails.

cssbundling-rails/lib/tasks/cssbundling/build.rake

Line 53 in 95d9b59

def tool_exists?(tool)

Probable cause is the above linked line.

   def tool_exists?(tool)
      system "command -v #{tool} > /dev/null"
    end

Since windows doesn't have a /dev/null directory, that line of code is platform-specific and fails on windows.

Versions:
windows 11
ruby 3.4.4
rails 8
cssbundling-rails 1.4.3

Seems like #176 fixes this issue.
