Add how-to guides

[jimbobbennett]

To help users get started quicker with basic tasks like saving snippets and chatting with the copilot, we need some how-to guides.

These should be guided how-tos focusing on the following tasks:

• Save a snippet, then use it later
• Use a snippet as context for the copilot
• Ask the copilot a question
• Use IDE integrations like code lens

There should be versions for all the integrations, with a landing page for them all. We can then surface these directly from the integrations.

Hi @shivay-at-pieces. Do you mind if you could put the community contribution label instead of the internal one? I think it would be helpful to get the community involved in fixing this issue.
