Update release note for Lambda layers in console (#1273)

*Issue #, if available:*

*Description of changes:*
Add release note that new Lambda layer versions are not immediately
available in console. Will be removed once deployment to Lambda and
Application Signals consoles are complete.

Also updates release note to not show "-adot1" suffix for upstream Otel
versions.
