[issue28692] gettext: deprecate selecting plural form by fractional numbers

Ok, so 1.000 seconds, ok, LGTM.

Should we mention something explicit about it? Not sure how to write it down, but I still fear that everyone's reaction will be "Oh can't give a float? Let my put a round() in my call" and stay with the same plural bug as before.

Maybe replace

> Plural value must be an integer

by

> Should not use ngettext with floating point, consider an invariant form.

?
