Add tags to the resources and add a section to filter resources by tags

## Problem

Currently, there is no tag to differentiate the resources as articles, blogs, news, workshop, webinar, tutorial or FAQs.

## Description

- We can add tags to the resources and also add a section on the left side to filter the resources based on the tags chosen by the user.
- By default, all the resources will be shown
- A panel with tags and checkboxes can be added on the left side from where tags can be chosen.
- This will help in filtering resources according to need and hence improve the UX for finding and accessing resources
- Add the tags at the bottom of the thumbnail of the resources for more clarity

## Implementation

- [x] I would be interested in implementing this feature.
