Language selector component: incorporate sync feedback

[jonadecker]

Takeaways from sync with Dan:

• Simplify link structure to allow link semantics to drive screenreader (no aria-label, no title)
• Add English language label after native language label in list-item, e.g., Español (English)

[mitchmoccia]

This is complete. aria-label and title have been removed and the text content updated to "Native language (English translation)"
