Update - Why Angular

[AbdellaToronto]

Why Angular

• [x] Generally feels a bit out of date, more of a comparison with AngularJS than why picking Angular today is valuable
• [x] Todd Motto link broken: https://ultimatecourses.com/blog/angular-component-method-back-ported-to-1.3
• [ ] TypeScript paragraph could be re-written?
• [x] New Features section out of date
• [x] Differences table needs to have column header shift right?
