Pull request overview

This PR adds a last resort fallback mechanism to the KubernetesDateTimeOffsetConverter to handle DateTimeOffset parsing for edge cases not covered by the strict RFC3339 format variants. The change aims to make the parser more lenient by falling back to general DateTimeOffset.TryParse when specific format parsing fails.

• Introduces a static StandardFormats array to avoid repeated array allocation
• Adds a fallback using general DateTimeOffset.TryParse with DateTimeStyles.RoundtripKind
• Removes redundant array allocation in line 52 by passing the format string directly
