Release v0.55.0

[gueniai]

• Introducing UCX docs! (#3458). In this release, we introduced the new documents for UCX, you can find them here: https://databrickslabs.github.io/ucx/
• Hosted Runner for release (#3532). In this release, we have made improvements to the release job's security and control by moving the release.yml file to a new location within a hosted runner group labeled "linux-ubuntu-latest." This change ensures that the release job now runs in a protected runner group, enhancing the overall security and reliability of the release process. The job's environment remains set to "release," and it retains the same authentication and artifact signing permissions as before the move, ensuring a seamless transition while improving the security and control of the release process.
