Declare experimental features as stable

[bastelfreak]

Use Case

It's confusing for users to check through https://www.puppet.com/docs/bolt/latest/experimental_features and notice that some stuff is experimental for months or even years. It's very confusing to users to see no progress and harms paying customers. Why are features marked as experimental for so long?

Describe the Solution You Would Like

Declare some of the functionality as stable if there are no known bugs. For example parallelize(), background() and wait().

Describe Alternatives You've Considered

I don't know, use ansible?

Additional Context

Again this was raised multiple times on Slack but nothing moved forward.
