Rework spellchecking, add `lint-spell` (#29106)

- 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- Remove inaccurate and outdated info in docs (we do not need GOPATH for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.

-**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。
