关于 BUVID3 获取方式

[Colerar]

其实只用带正常浏览器 UA 访问一下 https://www.bilibili.com/ 即会下发 Set-Cookie 头，可通过对应框架的 cookie jar 功能获取：

❯ curl 'https://www.bilibili.com/' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/116.0' --compressed  --cookie-jar output.txt > output.html

❯ cat output.txt
# Netscape HTTP Cookie File

web 端丢失后会调用 spi 接口，返回 3/4 的 buvid，姿势比较优雅，这样拿 cookies 没必要

#338 提供了通过 API 仅获取 buvid3 的方法, 但这 PR 好像没人管...

	## buvid
	```shell
	curl -H 'Host: api.bilibili.com' -H 'sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="99", "Google Chrome";v="99"' -H 'accept: application/json, text/plain, */*' -H 'sec-ch-ua-mobile: ?0' -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36' -H 'sec-ch-ua-platform: "macOS"' -H 'origin: https://www.biligame.com' -H 'sec-fetch-site: cross-site' -H 'sec-fetch-mode: cors' -H 'sec-fetch-dest: empty' -H 'referer: https://www.biligame.com/' -H 'accept-language: zh-CN,zh;q=0.9' --compressed 'https://api.bilibili.com/x/web-frontend/getbuvid'

	{"code":0,"data":{"buvid":"A2E7E681-1DE4-623F-8B08-B56D73F6C6C169792infoc"}}

于是在 #1088 添加了一段
