Redundant variable latestURI when checking header

Lines 163 to 167 in cbebe01

	if (sn === shortname) {
	latestURI = linkLate.textContent;
	} else if (sn === seriesShortname) {
	latestURI = `https://www.w3.org/TR/${shortname}/`;
	}

latestURI is assigned but never used.

latestURI was used to extract the document's body, and compared with previousURI body, to make sure they refers to the same document. previousURI is no longer used in Process Document 2021.

So latestURI could be removed.
