Update projects page name and sort projects by recently updated.

[hiyaryan]

Update the page title and url endpoint of "Projects" to "Portfolio". This allows for a larger encapsulation of my software engineering experience from projects, educational experiences, and business endeavors.

Also, the order that notion returns the projects is not in the order in which they are inserted into the database. The ordering doesn't seem to be clear but regardless of manually moving them around in the database, the order of the projects remain the same. This will require algorithmically sorting the projects on the client side to fix this. A good way to sort the projects could be by priority or by recently updated (which will require GitHub API and is currently the selected choice).
