Fixing the gradle version to 8.7

[f-galland]

Description

This PR fixes the docker images gradle version to 8.7, just before their InstallationLocation constructor was modified.
As detailed in the issue, there is already a merged PR from opensearch, but it's beyond version 2.15, so this is a temporary fix.
