What problem does this address?

Paragraph blocks do not have a gradient color option.
This feature was requested during user testing.

EDIT: This was done for backgrounds in #43119 but there is also a suggestion that we should be able to add graidents for text!

What is your proposed solution?

Enable support for gradient controls for the paragraph block.
