Use Sprig template functions

[fahhem]

What would you like to be added:
https://github.com/Masterminds/sprig

This library provides ease-of-use helpers, like split and replace.

Why is this needed:

Currently, I cannot use system.dmiid.product_name because the value has a space in it, and spaces are disallowed in labels. If I could do {{.Value | replace " " "-" }} it would fix it for me. As a result, I have to match the product_names I expect and manually write labels for them.

This will be true of any data that's not controlled by the cluster operator to be put into the content of a label.

Thanks @fahhem for the suggestion. This would be a very good enhancement. Would you be willing to work on this? 😉

The same issue has been discussed also here:
https://kubernetes.slack.com/archives/C01A82FKSQK/p1736747630626349

In addition, we could add some nfd-specific functions, say labelize to sanitize a value to be accepted as a kubernetes label value.

Thanks @marquiz, sent a PR to do this: #2038

I went with asLabelValue vs labelize because the key of a label has more limitations and I'm not ready to re-implement one of these functions in Go: https://github.com/kubeflow/kfp-tekton/blob/master/sdk/python/kfp_tekton/compiler/_k8s_helper.py#L20

That's good 👍
