chore(logo): add Quarto trademark logo and recompile PNG image

[mcanouil]

Add SVG file for the Quarto trademark logo and update the PNG version accordingly.

The SVG for the logo alone uploaded by @cwickham is a little bit different from the one I have from 2022 and is more consistent with the trademark version.

This PR does not update it. (https://github.com/orgs/quarto-dev/discussions/14672)

The main difference is the use of style instead of the fill attribute on the path elements. Should we use the SVG below for consistency with the trademark version, both made at the same time in 2022?
