Issue number: internal

What is the new behavior?

• Added focus styles on tab for the ion-select, using the --highlight variable.
• Adjusted highlight tests to work for ionic as well, just for the outline type.
• Fixed select border-color token used and updated snapshots (this affected all ionic theme snapshots for select). Although not directly related to focus task, the incorrect color was making it very hard to see the differences between the focus colors.

Does this introduce a breaking change?

• Yes
• No
