Add "Worksheet Name" selector to Cloud Office Excel Macro

The Cloud Office Excel Macro experience was updated in June 2022: https://support.atlassian.com/confluence-cloud/docs/insert-microsoft-office-macros/

This experience introduces a tabbed display of spreadsheets. However, all spreadsheets display & there is no option to narrow down the display to one spreadsheet. The suggestion here is to add an optional "Worksheet Name" selector to the Cloud macro.

If the "Worksheet Name" is filled out, the display would just show one worksheet. If it was left blank, the current tabbed experience would show.
