Declare @ember/string as peerDependency

[mkszepp]

The addon is using @ember/string, but there is not declared as peerDependency.

ember-cli-clipboard/addon/modifiers/clipboard.js

Lines 1 to 6 in 63c624f

	import { modifier } from 'ember-modifier';
	import ClipboardJS from 'clipboard';
	import { isBlank } from '@ember/utils';
	import { capitalize } from '@ember/string';
	import { guidFor } from '@ember/object/internals';
	import { macroCondition, dependencySatisfies } from '@embroider/macros';

I'm seeing Webpack throw test errors due to this issue:

message: ember-cli-clipboard tried to import "@ember/string" in "ember-cli-clipboard/modifiers/clipboard.js" from addon code, but "@ember/string" is a devDependency. You may need to move it into dependencies.

This occurs when bumping @ember/string from v3 to v4, likely because it's now a real module which requires ember-auto-import/embroider to consume. See also: emberjs/ember-string#425
