CHANGELOG: call out lexicographic version ordering

+* core: fix plugin version ordering to not be lexicographic. This fixes an issue
+     with how plugins are discovered by Packer, and ensures proper version ordering.
+     This means that with this change, versions that are semantically greater,

+     `1.0.10 > 1.0.9`
+
 ### IMPROVEMENTS:
 * core: Move to predictable plugin loading schema -  Packer will now only load
      plugins stored under PACKER_PLUGIN_PATH using the expected namespaced
