We use dump_ast_matchers.py script to update this auto-generated file in case someone make changes to ASTMatchers.
It wasn't enforced in CI so people didn't know or forgot to run it. We should enforce it in CI as part of premerge code-format job.
The idea is to run this script on code and check if it changed any lines. If it didn't change any lines - developer already ran it. If it did change some lines - the developer didn't run locally, thus they should do it and update their patch.
