Set release status flags based on info from the regressing bug 1878605

This is expected as we added a new version of a library in the tree, but can't still remove the old one as it's still used.
We'll be able to remove https://searchfox.org/mozilla-central/source/devtools/client/shared/sourceeditor/codemirror when Bug 1773246 is done, which should reduce the installer size
