Major.minor versions that end with 0 like 1.30 are truncated like floats

[pmalek]

Problem statement

When a version that ends with 0 like 1.30 is used in the config e.g.

render:
  kubernetesVersion: 1.30

then it will be truncated like a float number, i.e. 1.3.

Workaround

Use quotation marks:

render:
  kubernetesVersion: "1.30"

Proposed solution

Handle this inside crd-ref-docs so that users are not surprised.
