As discussed in https://github.com/spring-projects/spring-boot/pull/44394, the property has been deprecated since 3.2 when management.opentelemetry.resource-attributes was introduced as its replacement. It should have been removed in 3.4 but we missed it. To avoid a breaking change in a 3.4.x maintenance release, remove it in 3.5.

🙄 That's what I get for running the build with Docker disabled.
