Subject: [PATCH] [depre] Remove strict-booleans set deprecated since 2025-10

The set has been deprecated for 9 months and shrank to a single rule,
DisallowedEmptyRuleFixerRector, which the code-quality set already
registers. The "strictBooleans" flag of withPreparedSets() only printed
a warning, it never added the set to the config.
