Inconsistent algorithm and data model for encodedList

[PatStLouis]

The BitstringStatusListCredential data model defines the encodedList as follows:

The encodedList property of the credential subject MUST be a Multibase-encoded base64url (with no padding) [RFC4648] representation of the GZIP-compressed [RFC1952] bitstring values for the associated range of verifiable credential status values.

The Bitstring Generation Algorithm gives the following instruction:

Generate a compressed bitstring by using the GZIP compression algorithm [RFC1952] on the bitstring and then base64url-encoding (with no padding) [RFC4648] the result.

I suggest to add instruction to produce a Multibase-encoded base64url (with no padding) [RFC4648] representation of the GZIP-compressed [RFC1952] bitstring value to the algorithm.
