Short form of ordinal number

[Intelligent2013]

Currently, the spell out edition contains 'word':

<edition language="en">second edition</edition>

But, in the old ISO documents, the edition number is digits with suffix:

• 'en':
  

• 'fr':
  

NOTE: the word 'EDITION' should be uppercased.
NOTE: ème should be encoded in sup tags.

@Intelligent2013 which ones? Will implement in only 1951 for now.

@opoudjis 1951 is ok.

The Twitter-CLDR-rb library renders French "2nd" as "2e" not "2ème"; that of course is a stylistic preference in French, and the fashion (and the French National Printing House, which sets French printing style) has turned away from 2ème and towards 2e as simpler: https://lafaqdefrancais.wordpress.com/2022/01/23/abreviation-des-ordinaux-premier-premiere-deuxieme/

I could introduce older ordinals in Metanorma, but frankly, I don't see the point. 2<sup>e</sup> ÉDITION it is.

Note that this needs isodoc as well, since I introduced into its YAML the rules for digits + ordinals.
