feat: add console open support for S3 storage buckets

[gpoul]

Description of changes

Added console open support for S3 storage bucket; before this change it would just display "to be implemented..."; one of our participants ran into this during an Amplify Photo Sharing Workshop.

Description of how you validated changes

Tested in an empty amplify project before & after adding a storage component.

Hi @gpoul, thanks for the contribution! Are you still interested in working on this?

There's a lot going on the last weeks; If it is fine for you I'll follow-up mid August unless someone else has progressed it until then, but I won't have time before that. I'm still motivated to do it, though.

Hey @gpoul - just following up here. Are you still interested in moving this forward?

[gpoul]

@danielleadams I've now applied most of the feedback and followed up on one open point that still needs to be addressed

[gpoul]

@jhockett would you be able to look at this again? No real changes other than what you requested and me squashing the commits to make the history clean

[jhockett]

Hi @gpoul, I'm very sorry for the late reply, somehow I missed your ping back in September.

#10981 adds the same feature as this PR. Since 10981 includes unit tests and adds the console command for both S3 and DDB, I'm going to close this PR as a duplicate. We appreciate your contribution nonetheless!
