Description

The ping endpoint docs suggest the api version response header is:

API-Version

It is in fact canonical:

curl --unix-socket /var/run/docker.sock -i http://localhost/_ping
HTTP/1.1 200 OK
Api-Version: 1.44

Api-Version is the correct canonical format that headers should use and the docs could be updated to reflect this.
