Interactive function for diagnosing grammar version issues about clojure-ts-mode

[rrudakov]

Some major modes in emacs has workarounds for different versions of grammars (for example https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/typescript-ts-mode.el?h=emacs-29#n157). Would something like this work for clojure-ts-mode?

Indeed, I've submitted a couple bug fixes to Emacs for js-ts-mode where those version workarounds didn't work properly.

When tree-sitter-clojure or another grammar this mode depends on is inevitably updated we will have to use workarounds like that. In my experience those are very cumbersome to write and test. Mostly because there is no way to tell what version of a grammar is loaded.

Depending on the nature of a future grammar update, that may mean users of the latest grammar get more features than those using an older grammar. If a user wonders why they aren't seeing some new fancy highlighting then the functionality described in this issue would help them figure out why.

tree-sitter-clojure is pretty stable though, and the only other grammar we depend on is a markdown grammar, and in that we only query for 1 type of node. Because there isn't a great need for this this feature at the moment, it is low on my priority list.
