Remove unnecessary sleep between test runs

The introduction of `sleep` between test runs in `dashboard_spec.js` and `detector_list_spec.js` was initially implemented to handle timing issues. However, these tests were actually failing due to a recent URL change, as detailed in opensearch-project/opensearch-dashboards-functional-test#1257.

With the root cause of the failures addressed, the delays introduced by `sleep` commands are now redundant and can potentially slow down the testing process without providing any benefit. This PR removes these unnecessary sleep intervals between test executions.

**Testing Done:**
- Confirmed that all remote Cypress tests pass without the sleep intervals.
