pgstats.dev has been updated

In this update <a href="https://github.com/lesovsky">Alexey Lesovsky</a> made some important changes in <a href="https://pgstats.dev">https://pgstats.dev</a> - the dynamic realisation of PostgreSQL Observability diagram.
<p>We invite the Postgres community to discover the improved new look of this nifty tool. </p>

<p>Diagram changes:</p>
- views' and functions’ labels are now aligned,
- the arrows that used to show the link between the blocks and the stat labels have been replaced with colour scheme to show these relations,
- animation has been made smoother,
- readability of inactive items has been improved by increasing the opacity.

<p>Stat description pages (as in <a href="https://pgstats.dev/pg_stat_progress_create_index">here</a>) have also been updated to provide more information about future releases:</p>
- internal navigation has been improved by adding links to the related items,
- **resources** were added - external links to additional information,
- **versioning** is now there, so that you can see how Postgres evolved and when different features were added.

<p><a href="https://pgstats.dev">https://pgstats.dev</a> - now you can really observe Postgres!</p>
