We use [dump_ast_matchers.py](https://github.com/llvm/llvm-project/blob/main/clang/docs/tools/dump_ast_matchers.py) script to update [this](https://github.com/llvm/llvm-project/blob/main/clang/docs/LibASTMatchersReference.html) auto-generated file in case someone make changes to [ASTMatchers](https://github.com/llvm/llvm-project/blob/main/clang/include/clang/ASTMatchers/ASTMatchers.h). This PR ensures that `dump_ast_matchers.py` was run after change in ASTMatchers. Closes https://github.com/llvm/llvm-project/issues/165418.
