vulnerability

currently we have a version selector for every git tag, which is unnecessary overhead on the user. It is not needed from documentation perspective as there aren't (shouldn't be) any docs change in patch versions, only for new/changed features.

before:
v0.27.0, v0.27.1, v0.27.2, v0.28.0
after
v0.27, v0.28

What would you like to be added:

We can enrich the following subcommand by adding some details about the next update. For example, current db version, next db version, released datetime, is compatible, digest, etc.

$ grype db check
Update available!

Why is this needed:

For better UX and knowledge.
