@siddharthkp my thinking for picking minor was that this change seemed like it was adding functionality where a type was broadended to accept more values. Right now in our versioning doc we have that as a minor over at: https://github.com/primer/react/blob/main/contributor-docs/versioning.md#the-type-of-a-prop-is-broadened

Let me know if this seems more like a bug fix though or if it'd be worth talking about updating the version doc 👍
