Add more options for feature flag changelogs in docs
What does this MR do?
Feature flags are not only used for typefeature rollouts, they are also used for rolling out typebug fixes and typemaintenance works. However, in the feature flag changelog documentation, only "added" and "changed" are allowed for enabling the feature flag. In this commit, we are adding more options to the documentation.
