Add clj-kondo hooks for o/ruleset

[keychera]

Thank you for this great library. I plan to use this a more in the future so I made a clj-kondo hook to help lint my code.

With this hook, o/ruleset will have this the following linting properties

1. binding declaration for new symbols in :what block.
2. binding from :what block will be usable in :when and :then block
3. binding for session and match symbol in :when and :then block
4. binding for session symbol in :then-finally block (:then-finally block will have no access to match and bindings from :what block)
5. warning for usage of session and match symbol in :what block

I tested this in my 3 game projects that uses odoyle rules and the rules_test.cljc in this project using calva and all o/ruleset has no lint warning. the lsp feature like renaming and references work as expected as well. I also have confirmed the clj-kondo.exports is working correctly (in calva) by using this library as a git-deps of my fork. deps value below for convenience.

io.github.keychera/odoyle-rules {:git/sha "10447b7d8e3c9611fc9d59bc29d5a6d148d10556"}

There maybe edge cases that I haven't found so I am also gonna ask around for feedback with any other clojurians that uses this library.
