Governance: Add e2e test

[elliotxx]

What would you like to be added?

Need to be able to automate end-to-end testing of functions exposed on dashboard and integrate into github action.

You can consider using selenium or playwright framework.

Why is this needed?

Automated end-to-end testing can reduce the cost of manual testing and improve the stability of the project in the long run.

@n3A87 Hi 👋 Is there any problem?

[n3A87]

@elliotxx 我对这个issue的理解是，用playwright或者selenium测试框架编写脚本对karpor进行WebUI自动化测试。我理解的是否有偏差嘛？编程语言是否有限制？我计划是用python+playwright~但是最近两个月有点忙😭9月份才有充足的时间搞，7、8月空闲的时候会搞。

@n3A87 思路没问题的，这两个框架都是编写 web 端 e2e 测试的常用框架，选哪个都行。原期望是用项目主要语言 go 和 typescript 编写测试，不过 python 如果集成门槛不高的话，也可以。时间上看你方便，感谢参与社区 ❤️

@n3A87 实施的时候可以先在开发分支写一个 e2e 最小原型，提 pr 提前 review + 验证思路可行性（最好不要提超大 pr），实现上可以参考 gitea 的 e2e，它是 typescript+playwright 组合：https://github.com/go-gitea/gitea/blob/main/tests/e2e/example.test.e2e.ts
