update adapter version messages

[dave-connors-3]

Resolves #10230

Problem

The messages in dbt --version don't reflect the fact that the minor version of an adapter could be ahead of the minor version of dbt core

Solution

update the semver check in version.py!

I added the assertions for mypy's sake, but can be convinced to do that a different way

We should actually just rip this version checking logic out 🤔
