Update Twitter Icon Component to X (#724)

Refactor the "bird" logo to the newly rebranded "X" logo.

Used the official [logo](https://about.twitter.com/en/who-we-are/brand-toolkit)
from the brand tooling provided by Twitter, with a bit of resizing to fit
in the default viewports of (0, 0, 1792, 1792).

Fixes #723
