Is your feature request related to a problem? Please describe.
The Clojure Style Guide has a Use Idiomatic Namespace Aliases section which lists a set of namespace aliases. Adding a linter to clj-kondo to nudge developers towards adapting these community aliases in their own code would help increase the consistency of Clojure code bases.

Describe the solution you'd like
Add a linter that warns when using an unidiomatic namespace alias, where the idioms are defined in the Clojure Style Guide.

This can be implemented by adding a :community-guide flag to the :consistent-alias linter. Namespaces which have explicit configuration in the :consistent-alias linter should overwrite the :community-guide configuration, in case users prefer some aliases of their own, but generally want to adopt the community standards.

Describe alternatives you've considered
@borkdude suggested that alternatively there can be a new clj-kondo library created which would contain the community guide aliases so they could get merged to a project's clj-kondo config when imported. This option would require the minimal change to clj-kondo itself -- probably just documentation. On the down side, this approach may be difficult when installing clj-kondo as a binary instead of a project dependency.

Additional context
Currently, the Style Guide recommends clojure.spec.alpha -> spec which is likely a bug. There is an open PR which changes this item and some others. There should be some expectation of the alias list evolving over time.

@borkdude went ahead and put up the https://github.com/clj-kondo/configs repo which includes the recently updated set of community guide aliases.

You can opt in by putting this in your project dependencies:

io.github.clj-kondo/config-bbatsov-clojure-style-guide-aliases {:mvn/version "0.1.1"}

and then restarting clojure-lsp or running:

clj-kondo --lint $(clojure -Spath) --dependencies --skip-lint --copy-configs

Note that you can overwrite one more more of the entries by configuring your own :consistent-alias linter.

Marking this as resolved as it seems to cover all the bases. Thank you, @borkdude!
