used bootstrap to modify team page, added custom javascript file and included it in the layout.js

I created new team-page similar to the original one but using mostly bootstrap. There is some new css in style.css but most of the previous junk is gone. There is a new script.js file that acts like a custom script file - similar to how style.css acts as a custom styling file. The layout.html also loads the script.js file. I also changed the pictures used in the team-page to the webp format (as recommened in the igem hint or sth, there is a page dedicated to changing formats from png/jpeg to more web-optimised .webp). There is a new button functionality that changes the main team page.
