host + port is recognised as protocol

hasProtocol('localhost:3000')
// true

How do you think about solution? Technically something like mailto:[e-mail] is also valid protocol.

this is valid urn protocol, but not uri, maybe we can allow user to specific uri or urn in hasProtocol options? Probably it’s hard to do it in smart way.

tested with urijs (the largest uri package in npm), same issue found.

new URI('localhost:3000').protocol()
// 'localhost'

This kind of input is basically host (${hostname}:${port}) which we implicitly accept as valid input for various ufo utils. Sticking with a strict URL parser, it is true that behavior returns localhost as a scheme but this is kinda the DX point of ufo utils over using raw URL to allow more versatility on common inputs.
