FEDX-1997: adjust manageAndReturnTypedDisposable

[dustinlessard-wf]

Motivation

We intend to make a null-safety related change to w_common that is technically a breaking change in which over_react is the only consumer impacted. Rather than release a major, we intend to release the change as a minor and prepare an update pr to over_react ahead of time. This is that pr.

Changes

• Update manageAndReturnTypedDisposable to reflect the updated nullable bound, and that impacts over_react because the method is overridden.

Release Notes

• Update manageAndReturnTypedDisposable to reflect the updated nullable bound from w_common
