patch 9.0.0063: too many type casts for dict_get functions

Commit: https://github.com/vim/vim/commit/d61efa50f8f5b9d9dcbc136705cc33874f0fdcb3
Author: Bram Moolenaar <Bram@vim.org>
Date:   Sat Jul 23 09:52:04 2022 +0100

    patch 9.0.0063: too many type casts for dict_get functions

    Problem:    Too many type casts for dict_get functions.
    Solution:   Change the key argument from "char_u *" to "char *".
