Add prettier_d fixer path

Add prettier_d to prettier bin lookup

Could probably use a test, but this looks fine to me.

Will ale check for prettier_d or eslint_d that are installed globally with Yarn? I can submit a quick PR if this isn't the case.

No, but you can change your settings to point to that executable with the _executable and _use_global options. I recommend installing everything locally in node_modules.

Thanks for the info! I mistakenly thought that 'node_modules/.bin/prettier_d', was the global path that ale looks at, so I was going to add yarn's global path to the prettier fixer file (since I use yarn for global package installations).

Thanks for clearing that up for me :)
