Enable explicit-override by default in strict mode #17511

Feature

Tracking issue for enabling

[tool.mypy]
enable_error_code = ["explicit-override"]

When

strict = true

Pitch

As explained in PEP 698, strict enforcement of @override has many benefits.

When the Mypy developers feel that @override usage has had enough time for adoption in the community, enabling this by default when the user opts into strict mode would be helpful.
