GitHub integration - styling issues

[kyle-ssg]

Is your feature request related to a problem? Please describe.

There are a few stylistic changes that would improve the integration

Describe the solution you'd like.

These will look better if they are inline rather than on separate rows

Replace loading state with a center

Remove margin bottom from select options, just use standard styles

We are showing a no external resources linked as well as the ui to add in the center, this looks quite strange I think we have 2 options

1 - Left align the "You have no" text
2 - Remove the messaging

Linking an additional item UI should be above existing, it looks a bit strange it being underneath.

The save button feels unnecessary, we may as well just apply it when an item is selected

Link icon overflowing to new line

Describe alternatives you've considered
