Subject: [PATCH] Ignore unused lambda parameters in Eclipse

Since commit bda69f0ce2, Eclipse projects use a Java 24 baseline in
spring-core, so Eclipse flags unused lambda parameters (Java 22+) as
warnings. This commit configures the setting to be ignored, as is
already done for unused method parameters.
