Documentation: section with appendices titled "Appendix"

[Chealer]

The last section of the Spring Data JPA Reference Documentation contains 6 appendices. Although this is quite a lot more than one, its title is confusingly still "Appendix". "appendix" is singular. It can be pluralized as either "appendices" or "appendixes".

Thanks for letting us now. We should switch to Appendices across all projects.
