release prep for v1.11.0

[atravitz]

NOTE: we may want to merge in #1856 for v1.11.0, but I'm starting this branch to begin pre-release testing.

Make the PR:

• Create a new release prep branch corresponding to the version name, e.g. release/v1.2.0. Note: please follow semantic versioning.
• Check that all user-relevant updates are included in the news/ rever .rst files. You can backfill any additional items by making a new .rst, e.g. backfill.rst
• Run rever, e.g. rever 1.2.0. This will auto-commit docs/CHANGELOG.md and remove the .rst files from news/.
• Verify thatdocs/CHANGELOG.rst looks correct and that it renders as expected in the docs preview.
• If needed, create a release of the example notebooks repository and update the pinned release version in the openfe/docs/conf.py.
• Make the PR and verify that CI/CD passes.
  • feedstock packaging tests
  • example notebooks
  • GPU tests
• Merge the PR into main.
