add a different way to open the prototype in the vs code extension

[lucsomers101]

Challenge: When you miss the popup window you need to manually go to the correct adress.

Solution: The idea for this is to add a new way to open your portforwarded port adress from vscode. A few ideas currently are:

• An option in the menus
• An button
• Letting the popup stay open for longer
• Leave the popup open
• Opening the browser with the correct adress when command is run
