Bumped the spec to include fixes to SecurityGroup parameters

[Soupstraw]

Description

This PR fixes a conformance failure, which happens when an SPO tries to vote for a ParameterChange. Previously none of the parameters in the spec were in the security group, which meant that the SPOs could not vote for any protocol parameter changes.

Now that's fixed in the spec and this PR bumps the spec version to one where the security parameters are implemented properly.
