Missing dep hint (use e.g. --exclude="WebService::GitHub" to skip) is too naive for more complex deps

Zef recommends to use --exclude="WebService::GitHub", which doesn't help. Using --exclude="WebService::GitHub:ver<0.2.2>:auth<zef:raku-community-modules>:api<1>" does help though. Zef should recommend respectively.

I'm on zef v0.13.8.

Hmm, I'd expect the first example to still have worked since it should match WebService::GitHub:ver<*>:api<*> (aka WebService::GitHub) to WebService::GitHub:ver<0.2.2>:auth<zef:raku-community-modules>:api<1>
