Update README.md for SRA_Board_2023, LSA and MPU as per current changes

[dhairyashah1]

1. The images and references should be complete and within the systematic folders of this repository. eg assets.
2. Information should be updated, written properly in points with links to relevant work and in comparison to previous design highlighting improvements, what and why incorporated in this year's design.
3. Images, videos, or gifs should be scaled to uniformity.
4. Fixes and improvements with respect to the previous documentation are desired.
5. Links to relevant issues encountered and their solutions can be mentioned as well. I suggest linking this to blog posts later as mentioned in Create and Add web page for Board Hardware Documentation, posting test Blogs #18

@RajGupta17 seems like your fork is quite behind and is not in sync with many of the current upstream commits. Update that asap. Also include latest images of the board
