evolution: rename bumped to phase-divergent

Rename bumped to phase-divergent in all external user-facing output. Only
update user-facing output for the moment, variables names, templates keyword
and potentially configuration would be done in later series.

The renaming is done according to
https://www.mercurial-scm.org/wiki/CEDVocabulary.
