When on the "Explore Libraries" page, whether exploring a LAN library or Studio, a language filter should be placed in the the upper right corner of the page to make it easier to find channels by language.

This is distinct from doing a content search with the language filter in the side panel and returning content search results (i.e. resources).

Acceptance criteria:

• On "Explore Libraries" page, the language filter should be moved to the top right corner of the results
• The language filter should default to the current UI language
• The channel cards should be filtered by language, inclusively (i.e. a channel that has multiple languages should in included in the results if any of the languages matches the filter)
