Simplify description of --data-checksums in documentation of initdb 

The documentation mentioned that data checksums cannot be changed after
initialization, which is not true as pg_checksums can do that with its
--enable option introduced in v12.  This simply removes the sentence
telling so.

Use checksums on data pages to help detect corruption by the

may incur a noticeable performance penalty. This option can only
be set during initialization, and cannot be changed later. If
