[release/6.0] Backport deletion of playwright tests

[HaoK]

These tests were removed in 5247048 for 7.0, and due to pw having some infrastructure costs, better to remove these in 6.0 rather than update pw infrastructure

Hi @HaoK. If this is not a tell-mode PR, please make sure to follow the instructions laid out in the servicing process document.
Otherwise, please add tell-mode label.

Per discussion with @captainsafia and @TanayParikh these playwright tests were removed in 7.0 so this just backports their removal to 6.0 so we avoid any extra playwright issues

Thanks!

@wtgodbe this PR is green, is there any other process we need to follow to get this in, or is this sufficient for the build team to merge during the window?

[dougbu]

This PR is test-only. Any reason not to merge it @HaoK❔

[HaoK]

Nope, should be good to merge!
