"Don't ask again" User Experience improvements across DevHub

[petersalomonsen]

Similar to #687, but for whole DevHub.

What is covered here is improving of the "Don't ask again experience for":

• Creating a discussion
  • Notice the new SubscribedFeed.jsx component ( a copy of the original feed component ), which use the subscription parameter for receiving the feed index contents. This will automatically refresh every 5 seconds. (see notes over the video below about this)
• Submitting a proposal draft

This PR also reduce flaky tests by

• partly by using alternative RPC providers in some cases
  • Lava for fetching widgets
  • 1rpc for archive transactions
• ensuring await before expects, increasing test timeouts
• remove some expectations that are difficult to catch since it happens so fast ( which is the case for the loading spinner after the transaction has completed, it could still be there for a second or two in some cases, but it's hard for the test to expect this ).

Videos and issues

The video below shows the user experience when creating a discussion. Note the delay between that the spinner disappears and the discussion appear. The challenge here is that there is that Social.index cache invalidation is hard (haven't found a way yet) to trigger, and so I've configured the feed to subscribe every fifth second. The ignoreCache option of Social.index does unfortunately only work once per page session ( needs a reload ).
