It matches any tag version like started with "v" and a "." in the middle.
So v19.11.8 matches as at least one "." in the middle.
20.11_backport_202010506 can't match since it not started with "v"

Mentioned a little bit: "select the most early tag"
By default git output tag in alpha order, this makes v19.11 appears earlier
than v2.x, that's wrong.
