chore(deps-dev): update phpunit/phpunit requirement from ^9.0 to ^10.3

[dependabot]

Updates the requirements on phpunit/phpunit to permit the latest version.

Changelog

Sourced from phpunit/phpunit's changelog.

10.3.1 - 2023-08-04

Fixed

• #5459: assertStringMatchesFormat() should allow string type (not non-empty-string) for $actual parameter

10.3.0 - 2023-08-04

Added

• #5368: Control when PHP's garbage collector is triggered
• #5428: Attribute #[WithoutErrorHandler] to disable PHPUnit's error handler for a test method
• #5431: Add more garbage collector details to event telemetry

Changed

• Errors (E_USER_ERROR), deprecations (E_DEPRECATED, E_USER_DEPRECATED), notices (E_STRICT, E_NOTICE, E_USER_NOTICE), and warnings (E_WARNING, E_USER_WARNINGS) are now displayed grouped by issue
• When a test case class inherits test methods from a parent class then, by default (when no test reordering is requested), the test methods from the class that is highest in the inheritance tree (instead of the class that is lowest in the inheritance tree) are now run first
• Invocation count expectation failure messages have been slightly improved
• When a test case class inherits test methods from a parent class then the TestDox output for such a test case class now starts with test methods from the class that is highest in the inheritance tree (instead of the class that is lowest in the inheritance tree)
• TestCase::createStub(), TestCase::createStubForIntersectionOfInterfaces(), and TestCase::createConfiguredStub() are now static (and can be used from static data provider methods)
• The internal methods __phpunit_*() have been removed from the Stub and MockObject interfaces

Fixed

• #5456: Risky Test Check for Output Buffering is performed before after-test methods are called
