Auto Surround

you can have the same behavior with snippet but

• i got tired of having to create a snippet per each character
• the command when failing from realease to another #86954
• some chracters surround text as expected in some languages but not in other

so this extension fixes that for good.

Notes

• the extension doesn't need any configuration, just make a selection and press the surrounding key
• doesn't support inputs because its not exposed to api yet
