Description of changes

Port of #20488. Original description follows:

This PR makes the disabled prop in IDetailsRowStyleProps optional as it was introduced as an unintended breaking change by making it required.

It looks like this change to the 7.0 branch may not have been submitted to master yet. Now that version 8 has released, all changes must be submitted to the master branch first (except in emergencies or if the change is irrelevant to version 8).

Please do one of the following:

• If you've already created a PR to master, add a link to it
• If the change is irrelevant to version 8, add a comment explaining why
• Otherwise, create a PR to master with this same change, and add a link to it

After that, you can dismiss this review and remove the "needs cherry-pick" label (or ask a team member to help do so).

Want to avoid this in the future? Include text like "Cherry-pick of ####" in the PR description (where #### is the real master PR number).
