Add trademark symbol to DataFusion logo

[andygrove]

Is your feature request related to a problem or challenge?

As stated in the Apache Project Website Branding Policy,

Logos are important to recognize as trademarks as well. For the project's official logo (if it has one, and especially if it uses the ASF feather), ensure that it includes a small "TM" symbol in the graphic or immediately adjacent to it. For pages that include the project logo on them, ensure you mention "... and the Project logo are trademarks..." in the attribution.

Describe the solution you'd like

Add a TM symbol to the graphic ideally, or at least put one next to the logo in the published docs somehow.

This issue can be closed now because we are going with the new top-level Apache DataFusion logo instead (#8788).
