Implemented fetching articles from arXiv, pubmed, doi functionality & created resuable code & added countries select dropdown for location in createcommunity page

1. In the submit article page, I've added two things: i) Improved code reusability by replacing input fields with reusable components Input.jsx and TextareaField.jsx. ii) Implemented ArticleFetcher component which fetches the articles from the arXiV (ex: arXiv:2106.03744), pubmed (32572182), and doi (10.1007/s00134-020-05985-9)
   
2. In the createcommunity page, I've implemented two things
   i) Again improved code reusability by replacing input fields with reusable components Input.jsx and TextareaField.jsx.
   ii) Added countries select dropdown using react-tailwindcss-select library for selecting the location.

You are not adding the fetched article to the data base. Just fetching is not enough And Also the search bar design can be better.

You must provide a button to add that particular article to our database. And also check if its already added by anyother user before.

Understood. Redesigned the search UI and will try to add the functionalities related to the backend soon.

Looks great design. Can you also add "Add Article" Button to add article to database

[JyothiSwaroopReddy07]

Please Also add the Add Article button and using web-scraping techniques to scrap necessary and useful data which are not exposed by API ENDPoints of arxiv, doi. (pubmed I already Have done)

1. Added a shareable URL link for every comment (review) of the article.

2. Implemented the logic to fetch arXiv and doi articles and then add them to the database if that article hasn't been added before.
   

3. Enhanced Article UI section design by adding tooltips (for clear message) and enhanced style to buttons, text, and other icons
   
   The above is also proof everything's working fine without any breaking changes.

4. Added two unit tests for InputField and Footer using jest and @react-test-library. Also configured babel for parsing jsx files while testing.
