It seems like you've copied and pasted the same snippet repeatedly, and it doesn't appear to have any translations included

@rajatmohan22, Hey ya for translation i have done that cause i don't known every language. I have discussed this on discord from maintainers and they have told me to just put english translation in every language and raise a new issue to change them.

Although i have changed hindi myself as i am native hindi speaker and in rest of the case i have just put english translation.

After this pr get merged. we will open a issue to change all the translation.

Thanks for your work on this! We're about to upgrade our current CodeMirror version from 5->6, which will also touch on revamping some of its add-ons. Since a majority of this might look different from what's included in this PR, I'm going to close this for now. I'm sorry that we couldn't get this in, but please feel free to reopen this PR with any updates or check out our other issues!
