Add numTestsKeptInMemory to Cypress config

This commit modifies the Cypress configuration file to include the numTestsKeptInMemory option set to 10.
- This setting helps improve test runner performance and memory usage by limiting how many test results are kept in memory during test execution.
- No other functional changes or features were added.
