Subject: [PATCH] Add Section 8 to the PER-CS 1.0 to 2.0 migration guide

PER-CS 2.0 added a new normative rule to Section 8 requiring that
the `()` after `class` MUST be omitted when an anonymous class has
no arguments. The rule is not currently documented in the migration
guide. This commit adds the missing entry.
