Component

All of 'em.

Describe the bug

When you try to update a plugin while using blockly v8.0.2 npm is not able to resolve the dependency (as reported here: #1147).

Expected behavior

NPM should be able to resolve the dependencies.

Additional context

Instead of a version range like ^7 - 8 we should use >=7 <9. And when we release v9 of Blockly it should change to >=7 <10.
