[PR] docs: update 2.0.0 release notes and migration guide for latest merges [pekko]

["pjfanning (via GitHub)" <gi...@apache.org>]

pjfanning opened a new pull request, #3675:
URL: https://github.com/apache/pekko/pull/3675

   ### Motivation
   Several PRs merged today after the 2.0.0 release notes PR (#3606) were not yet in the release notes or the 1.x to 2.x migration guide. Both pages had also grown into long flat lists that are hard to scan.
   
   ### Modification
   **Release notes (`releases-2.0.md`)**
   - Add the missing merges: #3652 (Artery uid collisions), #3653 (EventWriter), #3644 (hand off timeout warnings), #3673 (fail fast with both Jackson modules), #3665 (ScalaPB deserialization fix, added to the #3651 entry) and the docs PRs #3655, #3658, #3660, #3663, #3664.
   - Add a serialization highlight to Main changes (marker traits, zstd, ScalaPB binding).
   - Move Security Hardening ahead of Bug Fixes.
   - Group Bug Fixes, Ported from Akka, Additions and Changes by module, using bold labels rather than headings so the page TOC stays short. No entries were dropped: every PR/issue link on `main` is still there.
   
   **Migration guide (`migration-guide-1.x-2.x.md`)**
   - Group the breaking changes by area: Java API, Actors, Streams, TLS, Remoting, Cluster Sharding and Persistence.
   - Add the Java DSL `pekko.japi.Function` removal and the Scala types replaced in Java APIs. Until now these were only in the release notes.
   - Move the `PekkoSSLConfig` migration from #3660 out of Dependency Changes into a TLS section and break it into steps.
   - Split the `SerializedEvent` note into its own bullet, and point to the single Jackson module rule from Dependency Changes.
   
   ### Result
   The 2.0.0 docs cover everything merged so far and are easier to read.
   
   ### Tests
   - Not run - docs only
   
   ### References
