Summary

By default our "See all posts" link goes to the designated "News & Stories" page. But it completely ignores the taxonomy filters of the block. The link is editable, so people can edit it but it would simpler if it automatically links to a filtered version of the "News & Stories"
page based on the choices already made for that block in the taxonomy filters.

Requirements

• Use filters that would already have in place for the "News & Stories" page
  • example: ?post-type=story&category=energy&tag=renewables
• Our dropdown filters should show the selected options (that's already the case)
• We should only pick one as we don't have a multi-select UI
• Adjusting the link url should be triggered every time an editor is making a change to the taxonomy filters.
