Add CHANGELOG for 1.2.1

[philippjfr]

Version 1.2.1

Date: 2023-07-18

This micro-release focuses on a small number of enhancements and rendering related bug fixes. Specifically it adds support for notifying users when the page is ready and when the Websocket disconnects using corresponding config options and upgrades the Vizzu version, thereby adding support for tooltips and enabling animations when the data is updated. The bug fixes are primarily focused on ensuring components such as GridStack and Tabulator render correctly and do not unnecessarily re-render or reload stylesheets. Many thanks and welcome to @owenlamont and @Sciemon for their first contributions to Panel and the maintainers @MarcSkovMadsen, @hoxbro and @philippjfr for contributing to this release.

Maybe explain that the performance fixes will make the ChatRow much more performant. Only a few persons would be able to understand why they are important.

They don't.

Fair point though, I'll add some explanation discussing what was improved.
