fix(agentic chat): Temporarily disable E2E tests

[opieter-aws]

Problem

E2E tests in Agentic coding experience are currently not working since the LSP is not set up correctly. This requires changes to the testing framework, which are still ongoing.

Solution

Disable the E2E tests so the CI passes, while the E2E tests are not updated yet

Old PR got closed with branch deprecation: #7213

After #7274 gets merged we will have inline tests working with flare, can we just skip the other tests for now?

We also probably need to let partner teams know
