Drush command patternkit:libUpdate has TypeError

Problem/Motivation

When you run the Drush patternkit:libUpdate command, it ends with a fatal error:

TypeError: Argument 1 passed to Drupal\patternkit\Commands\PatternkitCommands::updateBlockComponentPluginPattern() must be an instance of Drupal\block\BlockInterface, instance of Drupal\layout_builder\SectionComponent given

Steps to reproduce

• On a vanilla Drupal 9 site with "standard" profile, install these modules: patternkit_example, layout_builder, and patternkit_media_library
• Enable Layout Builder for a node type.
• On the Layout page for one of those nodes, add a Patternkit block, e.g., the one labeled "[Patternkit] Example".
• Save the block and view it.
• Modify that pattern's Twig template (modules/patternkit_example/lib/patternkit/src/atoms/example/src/example.twig).
• Flush caches and reload your node page. Notice that the new markup is not showing.
• Run the command to re-load changed Pattern templates: drush patternkit:libUpdate patternkit
• Expect to get the error listed above.

Release notes snippet

- Fixed a bug to avoid a TypeError in patternkit:libUpdate Drush command.
- Removed argument library_name from that command because it is not used.
