Move "Date updated" to the top of the page

[joverlee521]

The "Date updated" seems like an important piece of the build's metadata that should be displayed at the top of the page in the byline with the other build metadata.

auspice/src/components/info/byline.js

Lines 17 to 29 in 2e5792b

	class Byline extends React.Component {
	render() {
	const { t } = this.props;
	return (
	<>
	{renderAvatar(t, this.props.metadata)}
	{renderBuildInfo(t, this.props.metadata)}
	{renderMaintainers(t, this.props.metadata)}
	{renderDataProvenance(t, this.props.metadata)}
	</>
	);
	}
	}
