chore(python): pin the backend to 1.11.0

[github-actions]

@wdio/devtools-backend@1.11.0 is published, so the version a pip install user runs can move up from 1.10.0.

Opened by the npm release. scripts/check_backend_pin.py is what decides whether this pin is serviceable — it asks the published tarball whether it carries every contract name the adapter needs, so let that check run before merging.

If this PR shows no checks, it was raised with GITHUB_TOKEN, which GitHub will not let start a workflow. Close and reopen it, or push an empty commit, to get CI.
