🌱 Set v1.1.x to main branch, and release.

[guettli]

Previous PR: hcloud-ccm #1703
Next PR: #1775 (first beta2 PR)

Note

This is the last PR without beta2.
We should merge that to main (or reset main), and the release that to our commmercial customers.
After that we can work on beta2.

At the end of 2025 the main was reset to reflect the last release.

After this PR is merged to v1.1.x we plan to reset main again, and release caph v1.1.x

Tasks

• Update README.md and Pull-Request-Template to reflect the changes.
• Fix e2e tests.
• Maybe update CAPI to a newer version (which still supports beta1)
• Reset main
• Release
• Deploy
• Work on beta2
