Tree-sitter Java Grammar

The `tree-sitter-java` library provides the Tree-sitter grammar definition and source files for the Java programming language. It is designed to be used with the `tree-sitter` Python binding (or other language bindings) to parse Java code into a concrete syntax tree (CST) or abstract syntax tree (AST). The current version is `0.23.5`, and it follows the release cadence of the upstream Tree-sitter grammar.
