Update locales-pt-PT.xml

Thank you.
I have one doubt about this (all are masculine, but can also be feminine):

    <!-- LONG ORDINALS -->
    <term name="long-ordinal-01">primeiro</term>
    <term name="long-ordinal-02">segundo</term>
    <term name="long-ordinal-03">terceiro</term>
    <term name="long-ordinal-04">quarto</term>
    <term name="long-ordinal-05">quinto</term>
    <term name="long-ordinal-06">sexto</term>
    <term name="long-ordinal-07">sétimo</term>
    <term name="long-ordinal-08">oitavo</term>
    <term name="long-ordinal-09">nono</term>
    <term name="long-ordinal-10">décimo</term>


For example the first one in feminine should be:
<term name="long-ordinal-01">primeira</term>

Should it be like this:
<term name="long-ordinal-01" gender-form="feminine">primeira</term>

Thank you for your help.
