Portfolio :Save user data

[arnoldnekemiah]

I implemented the following

• When the user changes the content of any input field, the data is saved to the local storage.
• When the user loads the page, there is data in the local storage the input fields are pre-filled with this data.

Below is a link to my partner's contribution https://github.com/arnoldnekemiah/portfolio-new/commit/11ba3a77586510295bb4587daa1a5f3346d302ca

I removed some data which is only relevant for the Popup window, as we have not completed it yet :disappointed:
