Update to Spring Boot 3.3.0-M1

This commit updates the spring-boot-dependencies version to `3.3.0-M1`.

This update also transitively updates the AssertJ core library to
version `3.25.1` which introduces a deprecation for
`AbstractAssert#toList`. As such, these deprecated usages are replaced
in several tests with `AbstractAssert#asInstanceOf`.

Resolves #10
