Align RFQ reject message with BLIP

[ffranr]

This PR aligns the RFQ reject wire message with the BLIP changes found here https://github.com/Roasbeef/blips/pull/4 This PR is related to https://github.com/lightninglabs/taproot-assets/issues/871

These changes require a quote reject wire message version bump. We need to ensure that all RFQ breaking changes go into the same release. I've decided to spin them into their own PR because the scope of change is very narrow, these commits are small.
