Use WeblateOrg/weblate as a replacement for translate/pootle on the ASF Translation Service

• On Updates README to note that Pootle is not actively maintained translate/pootle#6926 and Status of that project? translate/pootle#6920, the Pootle community reached a consensus that Pootle actually lacks a maintainer, and a possible replacement was mentioned in Pootle's README, which is WeblateOrg/weblate.

• Maybe we can consider using WeblateOrg/weblate to replace translate/pootle on ASF Translation Service https://translate.apache.org/ ? translate/pootle is actually just a Web UI for https://github.com/translate/translate .

• https://github.com/WeblateOrg/weblate can also be used as a Web UI for https://github.com/translate/translate .

• From my perspective, only Apache OpenOffice is using ASF Translation Service.

• 

• I noticed https://cwiki.apache.org/confluence/x/vbOoAQ mentions that Infra started testing alternative translation schemes in 2020. What was the end result?

We did indeed test out alternatives, but in the end, it wasn't feasible for us due to the added maintenance cost compared with the low overall usage of the translation service. I think bringing the idea of weblate to the openoffice project would be the best path forward right now, as they are currently the sole maintainers of pootle at the ASF.
