fix(ui-color-picker,ui-color-utils): fix corrupted CJS build

babel-plugin-transform-imports cannot handle if there are multiple exports from a file. This commit
adds a default export which works with this plugin
TEST PLAN:
make sure the CJS builds do not try to run function from color utils without importing them

packages/babel-plugin-transform-imports/README.md

@@ -21,6 +21,8 @@ Note that any default imports you are currently using will not be transformed:
 import Text from '@instructure/ui-elements/lib/Text'
 ```
 
+Note that this plugin will fail if the exported name is not the filename! This means that it cannot handle multiple exports from the same file.
