Remove the Block Library module as it has composer issues

Problem/Motivation

Having #3205071: Switch Block Library module from ~1.0 to static require 1.0.0-alpha1 version
did not work as a temp fix for
#3205060: Fix issue with composer.lock on updates or install with composer.lock with found drupal/block_library[dev-master] but it does not match the constraint

Proposed resolution

Temp remove the module, then we add it back when they have the issue fixed
