I should see a sort option with 'Popular' and 'Alphabetical' options with the specified styling

[ibagha]

The user should see a sort option with 'Popular' and 'Alphabetical' when they come to the homepage.
Acceptance Criteria

• By default it's sorted and highlighted by popular
• When 'A-Z' is clicked, resources are sorted alphabetically by name, and the 'A-Z' text is highlighted
• When user types a search term, the filters should apply to that search terms. i.e, if I type in 'helm' into the search bar and select 'A-Z', the results for helm should be sorted by A-Z (same functionality as the discussion page on Concourse docs)

@ibagha Looking into backward flow, look into sort behavior when search term is used
