Update Github repo About session

[lephanthuymai]

"Please modify your GitHub repo description in the top right corner where it says ""About"" to include
A short description of your app (might already be there)
The link to your deployed dashboard (it is often useful to still keep this in the README as well)
A few keywords describing which plots, widgets, and interactions you have used in your dashboards, like I have done in my demo app.
If I have time during the break, I will use these to make a resource where you can easily find each others dashboards without searching through the public GitHub repos directly. I think this will be useful to reference back to for capstone and later. You can DM me on slack if your group does not want to be part of this for some reason."
