[Security] Remove unnecessary ghost colors from EuiBottomBar

[cee-chen]

Summary

👋 Hey y'all - EUI will shortly be deprecating the ghost color in all button components (see https://eui.elastic.co/v89.0.0/#/navigation/button#ghost-vs-dark-mode).

In this PR, all components using color="ghost" are being used within an EuiBottomBar and as such already automatically inherit dark mode coloring.

I'm opening this PR ahead of time for your team so you can test this migration and ensure no UI regressions have occurred as a result.

Checklist

• Tested in light and dark mode
