chore: bump test dapp 8.9.0

[seaona]

Description

This PR updates the test-dapp package used in our e2e tests to the latest version.
This will contribute into fixing an area of flakiness introduced by the WalletConnect PR, which was missing await in a couple of places, generating a race condition, which is now fixed in the latest version of the test dapp.

Fixes: #26009

Manual testing steps

1. Check ci, all tests should continue to work

Screenshots/Recordings

See example of the test dapp race condition, which makes a signatures test fail due to the wallet connect error and the popup never opens:
