Fix spell error from "Segmment" to "Segment" in the IRequestSegment interface

[rammi987]

Fund a spelling error, while using the IRequestSegment services. I saw that the service was correct spelled, along with the interface fil, but not the Interface itself.

Thanks for this contribution @rammi987. Unfortunately we need to tackle this in a slightly different way, so we adhere to our rules about obsoletion periods and avoiding binary breaking changes in minor releases. Would you be up for looking to re-work as I've suggested please?

All looks good to me now. I've also tested locally and verified that segmented content continues to be provided. Thanks for the contribution @rammi987.
