TRIB-233: fixes bug in ToBeReviewedCheckerServiceImpl

[mrsbluerose]

after updating to Spring Boot 3.3.1, some checks are less forgiving ToBeReviewedCheckerServiceImpl was throwing the following bug:

java.lang.IllegalArgumentException: method GET must not have a request body.
    at okhttp3.Request$Builder.method(Request.kt:258) ~[okhttp-4.12.0.jar:na]
    at org.springframework.http.client.OkHttp3ClientHttpRequest.executeInternal(OkHttp3ClientHttpRequest.java:88) ~[spring-web-6.1.10.jar:6.1.10]
    at org.springframework.http.client.AbstractStreamingClientHttpRequest.executeInternal(AbstractStreamingClientHttpRequest.java:70) ~[spring-web-6.1.10.jar:6.1.10]

Fix:

• Changes HttpEntity entity = new HttpEntity<>("", httpHeaders); to HttpEntity entity = new HttpEntity<>(httpHeaders);.
