queryAssignedElements decorator not included in import map

[zeroedin]

When using @queryAssignedElements you currently get the following error on the demo page:

Uncaught SyntaxError: The requested module 'lit/decorators.js' does not provide an export named 'queryAssignedElements'

I believe the issue is caused by docs/_data/importMap.cjs not including an import for that lit module.

Version 2.0.2 of lit does not have the decorator as an export, version 2.1.0 is the oldest version that does, not sure what all the ramifications are for changing any of the version numbers in this file.

That file only affects the eleventy build, so feel free to update it however you want. Might be nice to use a semver specifier like lit@^2
