Re: PG 16 draft release notes ready

Hi,

Thanks for making the release notes. I found the release note of
PG16 beta2 mentions a reverted following feature.

```
<!--
Author: Jeff Davis <jdavis@postgresql.org>
2023-03-09 [27b62377b] Use ICU by default at initdb time.
-->

<listitem>
<para>
Have initdb use ICU by default if ICU is enabled in the binary (Jeff 
Davis)
</para>

<para>
Option --locale-provider=libc can be used to disable ICU.
</para>
</listitem>
```

Unfortunately, the feature is reverted with the commit.
