Hmm, https://deploy-preview-49643--kubernetes-io-main-staging.netlify.app/bn/releases/ doesn't look happy does it? (compare https://kubernetes.io/bn/releases/)

Nope, it seems like its not picking up the website defined localisation keys

This time, it seems to work. I removed all the symlinks and moved all the files from data/i18n to i18n. I still think overrides aren't working so let me test that first.

/hold
Let's make sure we don't merge this. OK to unhold if we're sure that matches @SayakMukhopadhyay's intention.

This PR is ready for review. It contains 55 file changes but most of them (52 files) are just the translations moving from data/i18n to i18n.

The other 3 files include 2 files for removing the OWNERS from data/i18n and adding it back to i18n (git doesn't consider it as a move) and the 3rd file is the update to the hugo.toml which adds hugo mounts to it.

How confident are you that README and contributor docs changes are included here, @SayakMukhopadhyay ?

@sftim They aren't. I was thinking about updating the README about the changes in here in a new PR, unless you would like to have them in this PR itself.
