vale: exempt product names ending in '!' from Docker.Exclamation

The Docker.Exclamation rule flags any word followed by an exclamation
point in bare prose, which trips on product names that legitimately end
in '!' such as SDKMAN!. Link text and code are already exempt via
IgnoredScopes, but bare-prose mentions were not.

Add an exceptions list, matched against the word preceding the '!', so
genuine exclamations are still caught while listed product names pass.
