Update Example in Appendix A

[Mališa Vučinić]

Tag: WGLC follow-up

• Uri-Host option is not protected by OSCORE: remove brackets indicating authentication. Uri-Host is not present in the CoAP message from JP to JRC.

• kid_context is transported as part of OSCORE option. Same for Partial IV.

• Rename Object-Security option to OSCORE.

• Use of [] and {} is not consistent.
