Retitle "Recently Open Revisions" panel to "Recent Open Revisions"
Recently updated open revisions affecting this file.
...was simplified into:
RECENTLY OPEN REVISIONS
This is a bit misleading, since the panel doesn't contain "recently open" results. Use "Recent Open" instead, which is a bit more consistent with other product text. This is still slightly misleading, but probably close enough.
Test Plan: Read text.
