Release 0.11.1

[Lorak-mmk]

This is an emergency release to address #891
The steps I'll perform after this is approved:

• git checkout branch-0.11.x
• git tag -a v0.11.1
• git push origin v0.11.1
• git checkout main
• git merge --ff-only branch-0.11.x
• git push origin main
• Check that documentation was built and published successfully
• Create a github release explaining the purpose of the release
• cargo publish -p scylla-macros
• cargo publish -p scylla-cql
• cargo publish -p scylla
• yank scylla-macros 0.2.2
• yank scylla-cql 0.0.10
• yank scylla 0.11.0

After that I'll bump scylla-macros version on branch-0.10.x (will do a PR with this), and publish only scylla-macros crate

Pre-review checklist

• I have split my patch into logically separate commits.
• All commit messages clearly explain what they change and why.
• I added relevant tests for new features and bug fixes.
• All commits compile, pass static checks and pass test.
• PR description sums up the changes and reasons why they should be introduced.
• I have provided docstrings for the public items that I want to introduce.
• I have adjusted the documentation in ./docs/source/.
• I added appropriate Fixes: annotations to PR description.

One comment about the steps: please do cargo publish first and only then do a GitHub release - just in case something goes wrong during cargo publish.

Otherwise, LGTM.
