chore: Bump frontend package version and enhance test reliability (#7049)

* chore: bump frontend package version from 0.1.2 to 1.2.0 in package-lock.json

* test: enhance error message wait condition in generalBugs-shard-6.spec.ts

Updated the test to wait for the error message to appear with a minimum length of 20 characters, improving reliability in detecting error states. This change replaces the previous fixed timeout with a dynamic check, enhancing the robustness of the test.
