Conversely, why are we looking at the ICU version instead of the
collation version. If we have recorded the collation as being version
1234, we need to look through the available ICU versions (assuming we
can load multiple ones somehow) and pick the one that provides 1234. It
doesn't matter whether it's the same ICU version that the collation was
originally created with, as long as the collation version stays the same.
