Added patch for the X-Ray Remote Sampler

[AsakerMohd]

Description of changes:

Since upstream has updated the HTTP semantic conventions, the X-Ray Remote Sampler has been outdated as it's been looking at the older attributes that are no longer emitted. I've created a patch to temporarily fix this until the change is merged upstream.

To create the patch file:

1. Cloned the opentelemetry-java-contrib repo
2. Ran git checkout v1.39.0 to checkout to the same version used by the latest release (2.11.0)
3. Made the changes in the SamplingRuleApplier.java, SamplingRuleApplierTest.java and the version.gradle.kts files
4. Generated the patch file by running git diff > opentelemetry-java-contrib.patch. This should be a temporary patch. I'm creating another CR in upstream to fix this issue. Once it's fixed, we will need to update the io.opentelemetry.contrib:opentelemetry-aws-xray version to the latest one.

Testing:

Testing Setup:

1. Created a local build of the ADOT Distro by running the following:

./gradlew clean
./scripts/local_patch.sh //applies the patches including the new contrib patch
./gradlew build //this builds everything under the adot repo including the sample apps. 

2. Used the SpringBoot sample app which includes both the outgoing-http-call and the /aws-sdk-call APIs
3. Started the AWS Adot Collector in a docker container to retrieve Sampling Rules and to export traces to X-Ray
4. Started the Sample App using the following:

JAVA_TOOL_OPTIONS=" -javaagent:/Volumes/workplace/otel/aws-otel-java-instrumentation/otelagent/build/libs/aws-opentelemetry-agent-2.11.0-SNAPSHOT.jar" \
OTEL_METRICS_EXPORTER=none \
OTEL_LOGS_EXPORTER=none \
OTEL_AWS_APPLICATION_SIGNALS_ENABLED=true \
OTEL_AWS_APPLICATION_SIGNALS_EXPORTER_ENDPOINT=http://localhost:4316/v1/metrics \
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf \
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=http://localhost:4316/v1/traces \
OTEL_RESOURCE_ATTRIBUTES="service.name=$YOUR_SVC_NAME" \
java -jar /Volumes/workplace/otel/aws-otel-java-instrumentation/sample-apps/springboot/build/libs/springboot-2.11.0-SNAPSHOT.jar

Manual Testing:

For the manual testing. I created three sampling rules

1. Default one with zero sampling
2. Second one with path = /aws-sdk-call with 100% sampling
3. Third one with path = /outgoing-http-call with 100% sampling

Before the change, calling any of the above APIs wasn't being matched when it should. After the change, the rules were being matched and each rule showed the correct stats.

We need testing showing that this patch can takes effect and is working as expected.

Also please be more verbose in exactly how you generated this patch in the overview.

Quick thought: Do we need to do this in other languages?

I checked the other languages and we are up to date and we don't have an issue there. They're looking at both the old and new sem covs.
