[fix] Language selector for two languages has invalid ARIA attribute

[jaredcunha]

ReactUSWDS Version & USWDS Version:

There on the two-language variants of the Language Selector (button or link), there is an accessibility defect coming from aria-controls="language-options". An element with id="language-options" would not need to exist for this control.

While aria-controls might not be function, this is showing up as a violation in automated tooling.

To Reproduce
Steps to reproduce the behavior:

1. Click on the language selector button (or link)
2. Inspect element
3. Note the aria-controls attribute

Expected behavior

The aria-controls attribute should not be on this version of the Language Selector
