Replace "disable" and "enable" with non-ableist terms

In the spirit of #7554 (closed)

We think that we should move away from Ableist terminology.

The aspect that we see in our documentation and code relates to Feature Flags

In most cases, to toggle / activate / deactivate a feature, we currently use:

Feature.enable(:<feature flag>)
Feature.disable(:<feature flag>)

We'd like to consider moving away from such language. The current use of "enable" and "disable" is essentially a Boolean toggle, so here are some possible alternatives:

On : Off Active : Inactive

Written at the suggestion of @cnorris. As suggested by @ClemMakesApps , we should consult with the PM for feature flags.
