L10n,I18n: write an article about l10n, i18n, and why it could be useful to create basic items in any language

[SergeCroise]

• write a new article about l10n and i18n
• start a discussion e.g., in Mattermost
• brainstorming: discuss ideas about basic items in any language
• translate the basic items into supported languages
  (e.g., en-US, en-GB, es-AR, es-CO, es-DO, pt-PT, pt-BR, uk, af, de, es, id, it, nl, ...)
• sort the languages in the 文A combobox,
  the same order than https://crowdin.com/project/rockydocs (sort by:completed first)
• TM, MT, crowdin, etc.
• wiki: https://github.com/rocky-linux/documentation/wiki
