[Feat]: Add Tooltips to Copy and Merge Icons in Code Blocks

[superiorsd10]

Is your feature request related to a problem?

Currently, there are no tooltips associated with the copy and merge icons in code blocks within the FlutterGPT VSCode extension. This can lead to confusion for users who might not be familiar with the icons' purposes.

Describe the solution that you'd like

I propose adding tooltips to the copy and merge icons in code blocks. Tooltips will provide clear information about the functionality of these icons, enhancing the user experience and reducing confusion.
