Adds suppressions to pyrefly will typecheck clean: https://github.com/pytorch/pytorch/issues/163283 Test plan: dmypy restart && python3 scripts/lintrunner.py -a pyrefly check step 1: delete lines in the pyrefly.toml file from the project-excludes field step 2: run pyrefly check step 3: add suppressions, clean up unused suppressions before: https://gist.github.com/maggiemoss/4b3bf2037014e116bc00706a16aef199 after: INFO 0 errors (6,884 ignored) Pull Request resolved: https://github.com/pytorch/pytorch/pull/165659 Approved by: https://github.com/oulgen
