Resolve "Horizontal Scroll Bug"

Step 1: What is changing in this MR?

There's a horizontal scroll appearing on the pages when:

• The window size is from 1024px to 1140px
• The navbar has the 'talk to an expert' button

Dev notes

• I added some media queries to the navbar's CSS to fix those scenarios.
• Line 128 on src/components/Navigation/navigation-desktop.vue file was removed so the 'talk to an expert' button could appear, after the code review I'll add this line back.

Closes #147 (closed)
