Title: Move invalid body ID to body class and data

IDs cannot contain spaces. Instead, let's move jenkins-${h.version} to the `class` attribute, which is space delimited. This way it can still be used for styling if needed (using `body.jenkins-x.y`). If this is not used for anything other than knowing which version of Jenkins is running, use `

` -- IDs and Classes should not be used to store data.
