AnyUrl doesn't accept file URLs with implicit host #1983
Description
Bug
Output of python -c "import pydantic.utils; print(pydantic.utils.version_info())":
pydantic version: 1.5.1
pydantic compiled: True

import pydantic
class MyModel(pydantic.BaseModel):
url: pydantic.AnyUrl
MyModel(url='file:///foo/bar')raises:
ValidationError: 1 validation error for MyModel
url
URL host invalid (type=value_error.url.host)
However, MyModel(url='file://hostname/foo/bar'), i.e. a URL with an explicit hostname, works.
RFC 8089 says that the hostname is optional. Hence I would expect that AnyUrl would accept that.
