Table & AdvancedTable - Type fixes for isSelected

[dchyun]

📌 Summary

If merged, this PR would fix type issues found in the Table and AdvancedTable for the following argument.

• isSelected in the sub-component Tr
  • Change type from false to boolean
• selectionKey in the sub-component Tr
  • Update docs for type from string | number to string to reflect accurate argument type

🛠️ Detailed description

The type issues in the table components were caught while converting their showcase pages to TS.

isSelected

Currently in the sub-components Table::Tr and AdvancedTable::Tr the isSelected argument set to the type false. This means that anytime isSelected is set to true a type error is thrown.

The type has now been set to boolean and a getter has been added to set this.isSelected to false by default.

@dchyun for some reason the tests for the website are failing. I've tried to re-run the tests, but they failed again 🤷‍♂️

@didoo @shleewhite one of the files in the website for the icon didn't get updated to the new type name changes in #3063. Have a PR up to fix it in #3071
