Hindi translation no more available

[kulbhushanchand]

The hindi translation added as per commit #1888 , is no more visible in _data/ui-text.yml
I think it was mistakenly removed somewhere down the road.

Looks that way. Someone want to add it back?

Sure,
I have created two pull requests from the previous pull request (#1888) for the same.
#2105 (for main folder)
#2106 (for docs folder)
Please review.
