docs(man): omit misleading mention of environment for -u NORC (#16379)

The phrase referred specifically to `$VIMINIT` and `$EXRC`, which
are parsed (and available with, e.g., `echo $VIMINIT` if set) but
of course not loaded since _any_ initialization is skipped. Hence
this is redundant and can be misleading.
