[Cypress] Transaction details tests fix (elastic#199391)

## Summary
This PR re-enables the Transaction details cypress test, which was
disabled due to flakiness. The majority of the tests in this file needed
an increased timeout to run correctly. However, the 'Show top errors
table' test remains disabled, because it will consistently fail in
buildkite executing `.contains('a', '[MockError] Foo')`. This is
unreproducible locally, and no amount of refactoring or re-configuring
seems to affect the outcome.
