releaseCheck is not using exact string matches, but picks up substrings

Split out from January 2024 retrospective -

_https://ci.adoptium.net/job/build-scripts/job/release/job/refactor_openjdk_release_tool/8089/ was published with a name missing the `jdk-` prefix, but the releaseCheck.sh didn't show it as everything abnormal - it seems to have found the right release - perhaps because it was a substring of the 'real' value - something to look at it in the releaseCheck.sh script as a potential buglet._

Lee releaseCheck.sh y rastrea cómo compara los nombres de las releases con los datos de las releases de GitHub mostrados en el informe. Reproduce el caso en el que se acepta un nombre al que le falta el prefijo jdk- y, a continuación, verifica que solo pasen los nombres exactos y que se informe de la release anómala.
