feat: license tag filtering

[Alessandro100]

Summary:

closes MobilityData/mobility-feed-api#1567

Ability to filter licenses by tag

Expected behavior:

1. When you hover over the license, it will display all the license tags
2. You can select a license tag which will change the URL and display the feeds with the associated license tag
3. When the license tag is selected, it will show on the card to give user assurance that the filter is working

Testing tips:

Go on the feeds page and play around with the filter
