add a link to the vscode docs for colima users

[gedw99]

Might want to tell colima users about how to setup colima to play nice with vscode.

I guess make a heading in the REAMDE about "integrations" ?

Here is their docs on co-lima https://github.com/microsoft/vscode-docs/blob/main/remote/advancedcontainers/docker-options.md#macos-colima

It's on the website too https://code.visualstudio.com/remote/advancedcontainers/docker-options#_macos-colima.
