Subject: [PATCH 2/2] Remove foreign key constraint to avoid MAJOR version bump

Remove CUSTOMER_VISITOR_WEBSITE_ID_STORE_WEBSITE_WEBSITE_ID foreign key
constraint from customer_visitor table. The foreign key was causing
Semantic Version Checker to flag this as a MAJOR change, but it's not
required for functionality. The website_id column and index remain,
which is sufficient for the feature to work correctly.

This changes the version requirement from MAJOR to MINOR.
