As the line before what you quote says, it already is:

   https://git.savannah.gnu.org/cgit/nano.git/commit/?id=5b654ce9

(By the way: there is no default nanorc.  There is a sample.nanorc,
but most distros install this file by default as /etc/nanorc.)

It was in the NEWS file:

   2018.06.02 - GNU nano 2.9.8 "Espresso" brings the ability to filter the
                buffer (or the marked region) through an external command
                (^R^X and prefix the command with the pipe symbol, "|")...

Or more condensed in the IMPROVEMENTS file:

   Since 2.9.0:
     - The ability to filter text through an external command.

Looking at the help text (^T ^G) could have helped too:

   ...  If the command is  preceded by '|' (the pipe symbol), the current
   contents of the buffer (or marked region) will be piped to the command.
