test: make assertions order-insensitive to prevent failing tests based on Playwright version

[calvinbayer]

What does this PR do?

• Playwright tests are failing in the 5.81.0 release proposal PR
• During the migration to node.js asserts, the Playwright test assertions were changed from order-insensitive array comparison to order-sensitive comparison. The tests run against the oldest supported Playwright version, which depends on the dd-trace major version: on master this is v6 with Playwright 1.38.0, while on the v5.x branch it is v5 with Playwright 1.18.0. It looks like Playwright orders test execution differently in 1.18.0 than in 1.38.0, which is why the tests pass on master but fail on the v5.81.0-proposal branch
• Sorting the array before comparison allows to use the node.js asserts while restoring the old order-insensitive assertions
