Jump to resource definition feature

[ecoms-ye]

Is your feature request related to a problem? Please describe.
Not really, just when the template is too long, it's hard to find the resource.

Describe the solution you'd like
Like any programming language in vscode, use Ctrl+Click to go to the definition of a resouce from code like !Ref MyResource.

Describe alternatives you've considered
Since there is already a feature to show the resource's type like (Resource) MyVPC: AWS::EC2::VPC when hover !Ref MyResource. Maybe click this part then jump to the definition would be easier.

Additional context
Thanks for providing such a good extenstion!
