homepage-hero.svg redundant path

[arthurshlain]

Redundant pixelated outline path of letter B removed.

[patrickhlauke]

for the hero image itself, it's probably not that important, but note that just removing the extra path/outline makes the B slightly thinner (animation here to show the difference)

[mdo]

The path is intentional given the gradient inside the B—it provides a slight highlight. If you have tips for improving how it's rendered, I'm all ears! Otherwise, we'll leave it as-is :).
