Update csharp tree-sitter support due to upstream changes

Browse Source 
A change in tree-sitter-c-sharp grammar for csharp (commit
18a531), has removed the keyword void_keyword and advised
we should use predefined_type.
* lisp/progmodes/csharp-mode.el (csharp-ts-mode--font-lock-settings):
Support both old and new style of keywords in tree-sitter-c-sharp
grammar.  (Bug#65113)
