[njgreb]

• update .env example
• add MAX_PRICE_SERIES docs for AMD cpu's
• add ryzen cpu's as defaults if SHOW_ONLY_SERIES is empty

Description

Adds Zen 3 cpu's to the set of defaults if not filtered by config.

I think we'll also need to update this too:

streetmerchant/src/store/lookup.ts

Lines 161 to 185 in 5b3e95a

	if (store.labels.maxPrice) {
	let price;
	let maxPrice = 0;
	switch (link.series) {
	case '3070':
	price = await cardPrice(page, store.labels.maxPrice, config.store.maxPrice.series['3070'], baseOptions);
	maxPrice = config.store.maxPrice.series['3070'];
	break;
	case '3080':
	price = await cardPrice(page, store.labels.maxPrice, config.store.maxPrice.series['3080'], baseOptions);
	maxPrice = config.store.maxPrice.series['3080'];
	break;
	case '3090':
	price = await cardPrice(page, store.labels.maxPrice, config.store.maxPrice.series['3090'], baseOptions);
	maxPrice = config.store.maxPrice.series['3090'];
	break;
	default:
	break;
	}
	if (price) {
	logger.info(Print.maxPrice(link, store, price, maxPrice, true));
	return false;
	}
	}

But I'll make a following push! Thanks for adding this in! :D
