Update composer path on findComposer

[peter279k]

Changed log

• Update the composer execution path on NewCommand::findComposer command.

Actually, the original php compoer.phar string result is not correct.

And this will not specify the current path to let PHP binary know where the composer.phar can execute.

It should use the current composer path to tell PHP binary to execute composer.phar.

Instruction

I have already created the instructions on the original comments.

@peter279k you should have pinged Taylor about that. We can't know if you updated the original comment unless we check the "edited" history (which we don't always do). I see you've already created a new PR, thanks 👍
