keyvAdapter: support Keyv 5

[goto-bus-stop]

Keyv 5 was released today. It appears to have some issues, but once resolved It would be nice to support the new version.

Someone tried it already and got this type error: https://github.com/jaredwray/keyv/issues/1113#issuecomment-2301217699

@goto-bus-stop - you should be able to get this working now with v5.0.1

Different project, but yes it seems to work on my side

Therefore typing doesn't seem up-to-date, here's the related ticket: https://github.com/apollographql/apollo-utils/issues/459
