Update Gradle wrapper to use correct files

[asos-edgeorge]

Background

The local Gradle wrapper-related files within the project do not match the expected files for the Gradle version specified within the gradle-wrapper.properties file

distributionUrl=https\://services.gradle.org/distributions/gradle-8.7-bin.zip

This is likely occurring as the expected ./gradlew wrapper call was not previously used to upgrade the wrapper and the file was edited manually

To confirm this locally, you can run gradlew wrapper --gradle-version=8.7 --distribution-type=bin locally and observe there's a difference in a number of the related wrapper files

$ ./gradlew wrapper --gradle-version=8.7 --distribution-type=bin

What I've changed

This change contains the result of running the following command:

./gradlew wrapper --gradle-version=8.7 --distribution-type=bin --gradle-distribution-sha256-sum=544c35d6bd849ae8a5ed0bcea39ba677dc40f49df7d1835561582da2009b961d

Running the above locally within the project will ensure the relevant Gradle wrapper files for Gradle 8.7 are added.

Additionally, by providing the expected SHA-256 checksum for the Gradle 8.7 distribution (source) in this way, a distributionSha256Sum property is created within gradle-wrapper.properties which provides additional protection against Gradle supply chain attacks by ensuring future downloads via the distributionUrl are matched against the checksum and failing the builds otherwise.
