Non-existent section referred for key binding JWT rules due to a typo

[georgepadayatti]

Section 4.1. Key Binding JWT, says the following:

If the presentation of the SD-JWT VC includes a Key Binding JWT, the Key Binding JWT MUST adhere to the rules defined in Section 5.3 of [I-D.ietf-oauth-selective-disclosure-jwt].

But Section 5.3 does not exist in the referred spec. Instead, it should be Section 4.3

Thanks @georgepadayatti! A couple sections in SD-JWT were consolidated around draft 12 or 13 and other sections were renumbered as a result. We'll fix this reference and check for others that might need updating too.
