[flake8-builtins] Remove builtins- prefix from option names (#16092)

## Summary

Resolves #15368.

The following options have been renamed:

* `builtins-allowed-modules` → `allowed-modules`
* `builtins-ignorelist` → `ignorelist`
* `builtins-strict-checking` → `strict-checking`

To preserve compatibility, the old names are kept as Serde aliases.

## Test Plan

`cargo nextest run` and `cargo insta test`.
