valet share command needs support for ngrok -subdomain and -region params

[leonardoamx]

In Unix, you can type valet share [-subdomain=project] [-region=us] to define a custom url (project.ngrok.io or project.us.ngrok.io) but this package has valet share with no params.

I'm not using valet anymore, as I switched to docker years ago (life is so much easier now)), but you're welcome to submit a fix, as I understand this might be a help to someone. cheers.
