Fix pulling release notes

[johnoliver]

Currently when release notes are added it is required for a full update to be forced to pick them up. Find out why these are not being pulled incrementally.

Release notes are only refreshed during a fullUpdate() method: https://github.com/adoptium/api.adoptium.net/blob/9fd1254961d32b851374ec1cab5c30428eb8ad5c/adoptium-updater-parent/adoptium-api-v3-updater/src/main/kotlin/net/adoptium/api/v3/V3Updater.kt#L472

I suspect we need to tie the ReleaseNotes update into the github Release incremental update, so that when a Release updatedAt or binaryCount changes, a check for release-notes is done...
