[Feature] Add commands to the right-click menu of the worksheet in the sheets-ui plugin.

[FrontToEnd]

Initial checklist

• Is this really a problem?
• I have searched the Github Issues for similar issues, but did not find anything.

Problem

I want to disable the pop-up of the right-click menu, currently the onBeforeCommandExecute cannot prevent the pop-up of the right-click menu.

Solution

I can specify the right-click menu commands in onBeforeCommandExecute and prevent the menu from popping up by throwing an error.

I think it is a bug 🐞.
When contextMenu is set to false, the context menu of the sheet bar should not be opened. Don't worry about it, I will fix it soon.
