The language packs pages on the downloads site, such as https://download.moodle.org/langpack/2.7/ provide useful information on the percentage of language strings translated.

There was previously a language packs index page on the downloads site, however it was decided in the downloads reboot to link to lang pack downloads pages on the releases pages, such as https://download.moodle.org/releases/latest/.

Thus it would be good to have a lang packs index page on the translation site with links to https://download.moodle.org/langpack/2.7/ etc.
