[FEATURE]: Hindi captions translations for activities.html

[adityaraute]

Is this a unique feature?

• I have checked "open" AND "closed" issues and this is not a duplicate

Is your feature request related to a problem/unavailable functionality? Please describe.

Currently there are only English captions to all images in the json file.
After #103 is resolved, we will need to render Hindi captions on-click in the activities page

Proposed Solution

Implement a methodology similar to the one in index and contact html files
