Code Action "Add require" for namespaced keywords

[NoahTheDuke]

Is your feature request related to a problem? Please describe.
Currently, if you type in some-alias/some-var and then make a textDocument/codeAction request on the symbol, clojure-lsp will return a suggestion to "Add require '[long.name.example :as some-alias]". However, if you type in ::some-alias/some-keyword and then make a textDocument/codeAction request on the keyword, clojure-lsp will not return a "Add require ..." suggestion.

Describe the solution you'd like
Return two additional suggestions to the current set:

1. Add require '[long.name.example :as some-alias]
2. Add require '[long.name.example :as-alias some-alias]

Describe alternatives you've considered

1. Do nothing.
2. Delete the leading colons and then call codeAction and add the alias and then add the two colons back in.
