feat: add a filter feature to filter posts based on the options provided in the picture

[Siddharth1006]

Description

Its hard to find what the post is about until we click onto it. Like If there was a feature that allowed me to filter out all posts that are on the topic say - "Learning Resources" or if I wanted filter out posts on the different "opinions/perspectives" people had on different topic, that would be easier and more relatable. It would also solve the issue of searching for posts that are similar that I wish to read because they will be under 1 category.
