[K8S-535] charts/*: close values' schemas

Prior to this commit our charts' schemas were "open" which allowed extraneous
keys to be specified without repercussions. This had lead to many cases of
users having values files that "didn't work" due to incorrect key names,
indentation issues, etc.

As we're pushing out new major releases with breaking changes along side core's
25.1 release, this commit "closes" the charts' schemas which catch any
incompatible values or unexpected upgrades.
