Default button and outline variation have different padding

[itsamoreh]

On a fresh install, the default button and outline button have different padding.

Looks like this is happening because there are different numbers defined in theme.json for

"elements" : { "buttons": { "spacing": { ... } } }

and

"core/button": { "spacing": { ... } }

To reproduce:

1. Get a fresh install of wd_f on the main branch
2. Add a test page with a default button and a button with the outline variation
3. Observe that the padding is different
