Bump Cohere min version to limit backtracking on upgrade (#36666)

While testing #36537 I noticed cohere backracking quite a bit with
older version. Bumping Cohere to more recent minimum version
(released in November) decreased it quite a bit.

Since Cohere is mostly standalone package, and likely you want to
bump people to later version, it's safe to assume we can bump the
minimum version.
