Copy to clipboard when creating share link

[jwunderl]

Handles a few of the minor tweaks listed at the bottom of #146 -- copying to clipboard and aligning the language of the command. I left it emitting to the output window for now as a new link is generated every time / to match a bit closer with how it's shown in the webapp where we do show the link after it is generated:

I also noticed from the suggestion that commands in vscode tend to use title case for labels, so I'll do quick a pass updating that separately, as well as look at why it looks like we're activating the extension at all times and not just when these conditions are met https://github.com/microsoft/vscode-makecode/blob/main/package.json#L26

The Extension Host output channel should have printed a message when MakeCode got activated with the activation reason. Possibly microsoft/vscode#173992

Ah perfect thank you, you're correct that it's activating onLanguage:json, which would come from that issue as we do contribute .jres as an extension used for storing assets (images / songs / etc) https://github.com/microsoft/vscode-makecode/blob/main/package.json#L291.
