Explorers of Diem should be able to see mint and burn events

Business/User Value: As an Explorer of Diem I want to see mint and burn event information so that I can build trust in the system

### Acceptance Criteria
**GIVEN** I'm viewing the Diem Explorer
**WHEN** I click Events > Burn Events, or Events > Mint Events in the nav bar
**THEN** I'm taken to a page showing details of the 10 most recent burn or mint events respectively

**DEV NOTES**
* The two hasura tables we need to care about are `recievedmint_events` and `burn_events`
* There will be many event pages which will be very similar to each other
* Eventually we'll want pagination, but not now
*

Start at the Diem Explorer Events navigation and inspect existing event pages for their shared pattern. Trace the Hasura data for `recievedmint_events` and `burn_events`, then verify that Burn Events and Mint Events each show the 10 most recent records and are reachable from the nav bar.
