Homepage improvements

[gc]

This significantly reduces the size (5mb~ -> 1mb~) of the homepage, and makes the initial load smoother.

Changes

• Fix the "flash of loading spinner" visual bug, by not awaiting the fetch of the bootstrap.
• Convert the carousel images to webp, to make them significantly smaller.
• Lazyload the blog section on the homepage, so that a large video file doesnt download on every page visit.
• Convert the Runelite logo to webp, and make it smaller. (Its around 1000px, but only shows something like 50x50).
• Move the font-awesome css into the app.css file
• Remove the IE11 polyfill (internet explorer is EOL)
• Set the feature cards to have a low fetchpriority, as they are below the fold, and can impact load time of the visible images.

The "Latest commit:" label seems to be missing from the new homepage? Looks pretty nice at a glance

@Nightfirecat Weird, that worked locally. Should be fixed now in the last commit.

FWIW I still don't see the latest commit on the homepage anymore. I see it for ~1 frame, then it's hidden again

EDIT: False alarm, this computer was blocking requests from runelite.net to GitHub's API
