Unable to use gradients as colors for worldmap

[mlmaverick]

We recently upgraded the Superset version to 1.5.0 and I'm unable to deselect the Categorical Color Scheme for a heat map on the world map. From the what I understood, the colors schemes for a dashboard are now fixed to the dashboard but what do we do when we need to show gradients on the plot.

How to reproduce the bug

1. Create a dashboard with multiple charts and one of them is with country data on world map.
2. Create a chart with world map with gradient color scheme.

Environment

(please complete the following information):

• browser type and version: Chrome Version 102.0.5005.115
• superset version: 1.5.0
• python version: 3.8.12

Any help with this regards would be helpful. Thanks!

@mlmaverick Hey. We've added two color options in this PR to select categorical color or gradient color, so we might put this in the next release. cc @rusackas
