📝 Fix broken links in README.md

[vikasganiga05]

The link to run the project locally & the link to run the demo site locally are not correct. Both are missing the src directory.

How to Fix :

- http://localhost:8000/?user=DenverCoder1
+ http://localhost:8000/src/?user=DenverCoder1

- http://localhost:8000/demo/
+ http://localhost:8000/src/demo/

Screenshot :

The composer start script is set to run php -S localhost:8000 -t src which will set src as the root directory, so if you use this new script, the /src/ is not part of the url any more.

Oh! sorry, my bad. I didn't notice that.
