Detect git ssh protocols

packer.nvim errors when installing `use { 'ssh://git.company/repo' }`
I've tried `git@git.company/repo`, `https://git.company/repo`,
`git://git.company/repo`. None of these urls work with packer or with
`git clone`.

ssh, git+ssh, ssh+git are all names for git's ssh protocol. I tested
this locally and I'm able to install the package.
