Rework spellchecking, add lint-spell (#29112)

Backport clean cherry-picks of
9c39f8515f
and
c7a21cbb0c
onto 1.21.

- Use maintained fork https://github.com/golangci/misspell
- Rename `mispell-check` to `lint-spell`, add `lint-spell-fix`
- Run `lint-spell` in separate actions step
- Lint more files, fix discovered issues
- Remove inaccurate and outdated info in docs (we do not need GOPATH for
tools anymore)

Maybe later we can add more spellchecking tools, but I have not found
any good ones yet.

 接下来，[安装 Node.js 和 npm](https://nodejs.org/zh-cn/download/)， 这是构建 JavaScript 和 CSS 文件所需的。最低支持的 Node.js 版本是 @minNodeVersion@，建议使用最新的 LTS 版本。
 
-**注意**：当执行需要外部工具的 make 任务（如`make misspell-check`）时，Gitea 将根据需要自动下载和构建这些工具。为了能够实现这个目的，你必须将`"$GOPATH/bin"`目录添加到可执行路径中。如果没有将 Go 的二进制目录添加到可执行路径中，你需要自行解决产生的问题。

-**注意2**：需要 Go 版本 @minGoVersion@ 或更高版本。不过，建议获取与我们的持续集成（continuous integration, CI）相同的版本，请参阅在 [Hacking on Gitea](development/hacking-on-gitea.md) 中给出的建议。
