Resolve "[ENG] [i18n]: Homepage route is hardcoded in navigation"

Step 1: What is changing in this MR?

Issue's description:
We need to refactor our Navigation components to remove the hardcoded href="/" link on the logo. Our homepage now has translations, but the GitLab logo in the nav currently takes all users, regardless of selected language, to our English homepage. These links should be handled in our navigation.json file, with our logo's href being dynamic to a value in that file.

Our review app is still not working so to test this we need to run the branch locally or use the yarn link.
