Try to use import(..., { assert: { type: 'json' } }) for loading JSON configs

[bmish]

See:

eslint-doc-generator/lib/package-json.ts

Lines 79 to 82 in 4c527d5

	// For JSON files, have to require() instead of import(..., { assert: { type: 'json' } }) because of this error:
	// Dynamic imports only support a second argument when the '--module' option is set to 'esnext', 'node16', or 'nodenext'. ts(1324)
	// TODO: Switch to import() when we drop support for Node 14.
	return require(pluginEntryPointAbs) as Plugin; // eslint-disable-line import/no-dynamic-require

Unblocked since we dropped Node 14 support.
