Expand Testing Sidebar - Centrally locate all testing resources

What is the Problem Being Solved?

We have a few sections about testing dispersed throughout:

• zoe/contract-hello,
• contract walkthrough
• E2E Testing
• buildManualTimer

But nothing centrally, conveniently located that tells me:

• what types of testing options are available (unit, swingset, a3p, walletDriver, multichain, synpress)
• how to setup tests in my project
  • I would expect to be able to copy test setup and some example tests from the docs site

Description of the Design

1. The End-To-End Testing section should be expanded to "Testing" and include the following sections (sans parens):

   - Testing
   - Unit Testing (setupZoeForTest/makeZoeKitForTest, exo unit testing, mocked endowments*)
   - SwingSet Testing (runUtils, walletDriver)
   - A3P Testing (a3p docker images)
   - E2E UI Testing (synpress)
   - E2E Multichain Testing (multichain-testing / starship)

The sections should mention what each tool helps you achieve and when to reach for each.

*mocked endowments include things like:

• buildManualTimer (chainTimerService)
• makeFakeStorageKit (chainStorage)
• makeFakeBoard and marshaller
• packages/vats/tools/fake-bridge.js
  • LocalChain, Bank, and Transfer Bridges
• packages/orchestration/test/network-fakes
  • IBC vat and bridge and Network vat for orchestration testing
