some buttons still have orange ring/outline on dark theme

[LaurenWags]

Description

When using dark theme, some buttons still have an orange ring/outline. This orange ring/outline is not there in light theme.

Per discussion via https://bravesoftware.slack.com/archives/C01EVLWS8R5/p1726641052480589?thread_ts=1726626360.304599&cid=C01EVLWS8R5 there shouldn't be any orange.

Also found by @AlanBreck as well 👍🏻

Steps to reproduce

1. Be sure you are using dark theme (brave://settings/appearance > Brave Colors > Dark)
2. Open brave.com in a tab
3. Open a new tab
4. Type "brave." in the URL bar
5. In the drop down you will see an entry for brave.com with a button that says "Switch to this tab", this button has an orange ring/outline
6. In the URL bar erase what you've written and type ":br"
7. In the drop down you will see an entry that has a "Search Brave" button, this button has an orange ring/outline
8. If you repeat the above with light theme, there's no orange

(note, my step 6 and 7 have different button text in the screenshots below, but the premise is the same)

Actual result

Dark has orange, light does not

Dark	Light

Expected result

No orange in dark theme

@aguscruiz I think we should fix this by making the secondary color look less jarring next to the primary color - until them, I'm just going to make the TonalOutline the primary scheme, which is similar to what we do in Nala

However, I don't really see the point in our secondary colors if we can't use them.
