fix: sanitize kernel versions in enable-local-drivers-distribution

[kristina-solovyova]

Fixed an issue in enable-local-drivers-distribution WekaPolicy operation where kernel versions containing special characters (e.g., 6.6.105+ on Google COS) caused Kubernetes label validation errors when labeling nodes and creating driver builder containers.

P.S.: We should not run enable-local-drivers-distribution on Google COS, but maybe we will hit same issue in other OSes

Changes:

• Added sanitizeKernelVersionForLabel() and sanitizeForDNS1123() helper functions
• Sanitize kernel versions when setting weka.io/kernel labels on nodes
• Sanitize kernel versions in builder container labels and nodeSelectors
• Keep original kernel version in instruction payload for uname -r validation

Example: Kernel 6.6.105+ becomes 6.6.105 in labels, allowing driver builder pods to schedule correctly.
