Typo in references page

[ShubhankarKG]

Describe the bug

The reference page has a link named https://electronicsforu.com/resources/learn-electronics/flip-flop-rs-jk-t-dputting which is a typo error. This leads to a 404 on going to the site specified.

To Reproduce

Steps to reproduce the behavior:

1. Go to 'https://learn.circuitverse.org'
2. Click on 'references'
3. Scroll down to 'point 4'
4. Click the link to see error.

Expected behavior

A new page that opens up a specified reference resource.

Screenshots

Desktop (please complete the following information):

• OS: Ubuntu 18.04
• Browser: Chrome
• Version [e.g. 22]

Additional context

Two other things to note:

1. The Reference.md begins with a capital R. This is inconsistent with all files. Need to rename that.
2. The target: _blank without the use of rel="noopener noreferrer" is considered bad practice with respect to performance and security issues. Need to add that as well.
