[nongnu] elpa/cider 5631d60295: Reify cider-cljs-pending separate from repl-type (#3291)

[ELPA Syncer]

branch: elpa/cider
commit 5631d60295a623cbb161c76b70dac1305b1c0987
Author: Benjamin <38900087+benjamin-asdf@users.noreply.github.com>

    Reify cider-cljs-pending separate from repl-type (#3291)
    
    This pull request addresses #3287 by separating the concept of a repl type 
from the concept of pending cljs upgrade status. The pending variable is now 
set when the repl is initialized, and it is set to nil when we are sure that we 
have a cljs repl in cider-repl--state-handler.

 ### Changes
 
 - Bump the injected nREPL version to 1.0.
+- [#3291](https://github.com/clojure-emacs/cider/pull/3291): **Remove** the 
`'cljs-pending` `repl-type`. It is replaced by 
`cider-repl-cljs-upgrade-pending`.
