WRO-745: Clean up Spotlight document

[jeonghee27]

Checklist

• I have read and understand the contribution guide
• A CHANGELOG entry is included
• At least one test case is included for this feature or bug fix
• Documentation was added or is not needed
• This is an API breaking change

Issue Resolved / Feature Added

There is duplicated api description on Spotlight/index.md files.

Resolution

• Leave only the APIs that are mainly used and remove others.
• Add link for full api list
• Merge some docs in SpotlightContainerDecorator.js (There was nothing to merge in the Spottable docs.)
• In the md document, the term "Parameters" is used, but in the api documents and code, the term "Configuration" is used. So, I modified it to use "Configuration Parameters."

Additional Considerations

restrict is not an officially provided config, but it is used for initial setting in many places. (even in the Spotlight example)
So I thought restrict should be added to the SpotlightContainerDecorator docs
