Review comment:
Is this needed here? The FAQ should probably explain that the change
should be done in `superset_config.py`.

Review comment:
`SETUP_EXTRA` feels ambiguous, and will be difficult/disruptive to
change once introduced. Perhaps break this up into `EXTRA_COLOR_SCHEMES` or
even `EXTRA_CATEGORICAL_COLOR_SCHEMES` and `EXTRA_SEQUENTIAL_COLOR_SCEHEMES`
would make sense?

Review comment:
We should probably export this (and other related ones) in
`@superset-ui/core`.

Review comment:
Nit:
```suggestion
let color_schemes: ColorScheme[] = [];
if (
bootstrapData.common &&
bootstrapData.common.setup_extra &&
bootstrapData.common.setup_extra.COLOR_SCHEMES
) {
color_schemes = bootstrapData.common.setup_extra.COLOR_SCHEMES;
}
setupColors(color_schemes);
```
