Autocompletion doesnt work with dollar character

[awolkers]

When using a dollar character when importing the styles autocmpletion doesnt work, It only works when importing styles as a string name.

Doesnt work:
import $ from './SomeComponent.module.scss';

<SomeComponent className={$.someClassName}/>

vscode-css-modules/src/CompletionProvider.ts

Lines 21 to 33 in 3c0e729

	function getWords(line: string, position: Position): string {
	const text = line.slice(0, position.character);
	// support optional chain https://github.com/tc39/proposal-optional-chaining
	// covert ?. to .
	const convertText = text.replace(/(\?\.)/g, '.');
	const index = convertText.search(/[a-zA-Z0-9._]*$/);
	if (index === -1) {
	return "";
	}
	return convertText.slice(index);
	}

This Regex (line 26) will not match the dollar sign .
