What?

Updates the Tooltip custom delay unit test to use a larger additional delay buffer.

Why?

The test has been failing intermittently on trunk CI. Recent Unit Tests workflow failures showed the same assertion failing repeatedly:

Tooltip › delay › should respect custom delay prop when showing tooltip

The original test only left a 100ms gap between the default delay and the custom delay, which can be consumed by CI overhead before the "not visible yet" assertion runs.

How?

This keeps the behavior being tested the same, but increases the arbitrary additional delay from 100ms to 500ms. The test still verifies that the tooltip does not appear after the default delay, then appears after the custom delay.

Testing Instructions

Run the focused Tooltip test:

npm run test:unit -- packages/components/src/tooltip/test/index.tsx

Stress test the previously flaky test:

for i in $(seq 1 20); do npm run --workspace @wordpress/unit-tests test:unit -- packages/components/src/tooltip/test/index.tsx --testNamePattern='should respect custom delay prop when showing tooltip' || exit 1; done

Expected result: all runs pass.
