Custom Extension Modal Isn't Scrollable

[angiejones]

Describe the bug

When adding a custom extension, a model appears. By default, the buttons do not appear. I open the Goose desktop window to fullscreen on my large monitor and then can see the Add button but not any others.

After adding 1-2 environment variables, the height of the modal grows and the buttons are no longer in view. So I can't even click Add.

A workaround is to tab to the buttons and press enter, but I'd have to know the position of them since they are not visible.

To Reproduce Steps to reproduce the behavior:

1. Go to '...'
2. Click on 'Settings'
3. Scroll down to 'Custom Extension'
4. Add a few environment variables

Expected behavior A scrollable modal that allows me to get to the buttons
