find.1: fix rendering of find -s example

[rlibby]

Summary

The period here is part of the literal string in the example. Adding a
space caused the example to be quoted wrongly.

Test Plan

Before, and see https://man.freebsd.org/cgi/man.cgi?query=find&apropos=0&sektion=1&manpath=FreeBSD+15.1-RELEASE&format=html

For example, ‘find -s’ puts a directory ‘foo’ with all its
contents before a directory ‘foo’.  but ‘find | sort’ puts the
directory name ‘foo’.  before any string like ‘foo/bar’ because
‘.’ goes before ‘/’ in ASCII.  In locales other than C results
may vary more due to collation differences.

After

This will cause a linter complaint. You need to escape the period with a zero-width space.

Ditto.

ziaee feedback: use a zero-width space to keep the linter happy

Oh can you mfc it too?
