[DOCS#CI-2051]: Add missing 3.23.2 release note for auto-HostEndpoint controller fix - #3022
Conversation
The kube-controllers auto-HostEndpoint controller could panic on a node-deletion event delivered as an informer tombstone, intermittently leaving a rebuilt node without its automatically created host endpoint. The fix (calico-private PR #13434) merged into the release-calient-v3.23 branch ahead of the 3.23.2 cut but its release note was never added to the docsite.

Additional information:
Before: The Calico Enterprise 3.23.2 release notes page listed the other bug fixes shipped in that release, but omitted the fix delivered , even though that fix merged into the branch before the 3.23.2 cut.
After: Adds one bullet to the "Bug fixes" list under Calico Enterprise 3.23.2 bug fix release describing the fix: the kube-controllers automatic HostEndpoint controller could panic when a node-deletion event arrived as an informer tombstone, which could intermittently leave a rebuilt node without its auto-created host endpoint.
The wording is adapted from the equivalent upstream Calico OSS release note already published for this fix ("Fixes a panic in kube-controllers when the informer delivers a tombstone object to a delete handler", calico#13631), reworded to this doc's Enterprise release-notes style.
