PGZero logo doesn't appear right in Windows due to missing font

In the documentation the Pygame Zero logo is included as an SVG image. This means that it relies on fonts being available in order to render correctly.

We should convert the characters to paths so that they do not vary across platforms.

Inspect the SVG image used for the Pygame Zero logo in the documentation and identify its text characters and font dependency. Convert those characters to paths so the logo renders consistently across platforms, then verify its appearance on Windows.
