[operator] Reject invalid/unknown properties using `additionalPropert…

…ies` (#1065)

* [operator] Reject invalid/unknown properties using `additionalProperties: false`

This can catch misspellings like the one below, which I encountered when
using this Helm chart myself (but the previous validation did not catch it):

    Error: values don't meet the specifications of the schema(s) in the following chart(s):
    opentelemetry-operator:
    - (root): Additional property kubeRBACPRoxy is not allowed

* [operator] Bump operator minor version after validation update

 # Upgrade guidelines
 
+## <0.50.0 to 0.50.0
+
+Additional properties are not allowed anymore, so care must be taken that no old or misspelled ones are present anymore.
+`helm show values open-telemetry/opentelemetry-operator --version 0.50.0` can be used to list the allowed values.
+
 ## <0.42.3 to 0.42.3
 
 A type of flag `autoGenerateCert` has been changed, now it is an object with two attributes `enabled` and `recreate`.
