[CPDEV-100884] Validate that kubernetes images are not downgraded

[ilia1243]

Description

• If some kubernetes image version downgrades in the compatibility map, it may still not downgrade during Kubernetes upgrade.
• This leads to inconsistency of expected and actual versions, PaaS check may fail, and behavior of kubemarine add_node, kubemarine reconfigure is undefined.

Solution

• Validate that kubernetes images are not downgraded for allowed upgrade cases.
• The PR can be merged once the problem with downgrade of etcd for v1.28.8 -> v1.29.1 is solved.

Test Cases

TestCase 1

Steps:

1. Run scripts/thirdparties/sync.py

ER: Until v1.29.1 is the latest patch version for Kubernetes v1.29, the tools fails.
