A easy way to say to clojure-lsp to use cljs data to decorate core functions on squint projects

Describe the solution you'd like
Be able to declare this on .lsp/config.edn and having a dev alias on squint.edn with clojurescript as :extra-deps

{:project-specs [{:project-path "squint.edn"}]}

Should enable lsp to use cljs data on the analysis.

Describe alternatives you've considered
You can make this works currently with the following .lsp/config.edn file:

{:project-specs [{:project-path "squint.edn"
                  :classpath-cmd ["clojure" "-Spath" "-Sdeps" "squint.edn" "-A:lsp"]}]}

And having this on squint.edn file:

... 
:aliases {:lsp {:extra-deps {org.clojure/clojurescript {:mvn/version "1.12.42"}}}}
...
