Consider a minor docs re-do when it comes to <Names>

I couldn't help but notice that the docs say that `You can import AlphaPicker BlockPicker...` but then later in the docs all these elements are referred to as ``, `` and so on. Shouldn't they instead be ``, `` etc?

Start by locating the documentation passages that describe importing AlphaPicker, BlockPicker, and the other picker components. Update the later element references to use the corresponding component names, then review the surrounding examples to confirm the import and usage names are consistent.
