new theme for search button

[katydecorah]

This PR can be reviewed when we're ready to make the next release.

This PR updates the theme for the Search button:

• Uses Assembly btn classes for consistency
• Makes button a little more prominent, without drawing too much attention
• Uses accessible colors (current contrast ratio is too low)

@colleenmcginnis if we have time to review, this would be good to add in the next release!

I love this new style @katydecorah! I'm noticing the formatting gets a little messy in your example right before the break when the search bar jumps onto its own line:

Do you think that's something we can/should address?

@colleenmcginnis The test case was using code that we normally don't use in the topbarsticker, I updated it and it scales much cleaner!

Do you think that's something we can/should address?

This was related to code holding the search button and not specific to the search button itself.
