Pending upgrade release fix

[miklezzzz]

Overview

The following changes are introduced:

1. go was updated to 1.20 to support newer versions on the dependencies. (random seed generation is omitted as in 1.20 it's provided implicitly);
2. dockerfile was updated to provide up-to-date build instructions;
3. helm module logic was updated so as to apply helm upgrade every time when the module's release isn't in deployed state. All other release states are regarded as faulty.
4. helm resource monitor was updated to check not only for absent resources of the release, but the current release state (see previous point);
5. release recovery from pending state logic was updated to delete faulty revision and do helm upgrade if helm storage driver is Secrets or ConfigMaps. This way there is no need to do rollback and upgrade, thus, avoiding multiple consequent redeploys. If other type of driver is in use, standard rollback procedure is applied.
6. ListReleasesName method of the helm3lib package was fixed to list not only releases in deployed or failed states (by default), but all releases. It makes purge procedure slightly more robust.
