fix(rust/rbac-registration): Fix deleted tag cbor decoding

[bkioshn]

Description

Fix deleted tag cbor decoding for X509, C509, Simple Public Key
As defined
deleted-key = #6.31(undefined) ; delete the key (if any) at this position of the array
deleted-key is of tag 31 follow by undefined.

Ref: https://github.com/input-output-hk/catalyst-CIPs/blob/x509-role-registration-metadata/CIP-XXXX/x509-roles.cddl

Test

Test with slot = 86965717, tx_index = 0 Deleted for x509 certificate index 0

Original Error got Unknown tag for X509DerCert
