[release-1.3] Add OneAgent version validator

[albertogdd]

Description

https://dt-rnd.atlassian.net/browse/DAQ-1817

Same as #3966

But adding the validator also for beta1 (because different apiVersion validators are only merged on main)

How can this be tested?

Only DynaKubes with versions like this should pass the CR validation when applying:

spec:
  oneAgent:
    cloudNativeFullStack:
      version: 1.304.0.20240826-070516

⚠️ Test on v1beta1 and v1beta2
