[nrfconnect] Update nRF Connect version

[Damian-Nordic]

Problem

Supported nRF Connect SDK version is outdated. In particular, we need newer OpenThread version to fully implement commissionable node advertising.

Change overview

Bump supported nRF Connect SDK version, including the Docker image, and fix all related build issues.

Testing

Verified that commissioning and control of the nRF Connect Lock example still works correctly.
