fix: spawn jscodeshift cli using node

[merceyz]

What's the problem this PR addresses?

jest-codemods tries to spawn sh files on Windows by spawning node_modules/.bin/jscodeshift
Using require.resolve('.bin/jscodeshift') relies on an implementation detail that isn't guaranteed to exist (Yarn PnP) or point to the expected version of jscodeshift

How did you fix it?

Resolve the JS CLI directly and spawn it using node

Thanks for fixing this!

I'm curious why we never heard about this issue. 🤔

Seems execa reads the shebang and spawns the correct process but either way using require.resolve('.bin/jscodeshift') relies on an implementation detail that isn't guaranteed to exist (Yarn PnP) or point to the expected version of jscodeshift

Good point. Again, thanks for fixing this 👏
