test: increase retries by 1 for Playwright CI runs

[bosschaert]

Description

I noticed that some Playwright tests are still a little flaky when run through the CI/Github actions, especially ones that check async UI behaviour. We should make those more robust, but in the mean time let's increase the test retries by 1 until we have them more stable.

Motivation and Context

To avoid having to re-run the tests by hand.

How Has This Been Tested?

These are changes to the Playwright test runner only.
