Upgrade to PHPUnit 11 (#1885)

Address deprecation warnings:

> Targeting a trait such as Smr\Container\ResettableContainerTrait with #[CoversClass] is deprecated, please refactor your test to use #[CoversTrait] instead.

> returnValueMap() is deprecated and will be removed in PHPUnit 12. Use $double->willReturnMap() instead of $double->will($this->returnValueMap())
