[Error]: [markdown-preview.nvim]: Can not open browse by using cmd.exe command

I'm using the most current version of this nice plugin in nvim under WSL2. I'm using this plugin for while and it always worked fine, but it seems like any commit introduced a bug.

When running `:MarkdownPreview` the plugin retports this error:
```
[markdown-preview.nvim]: Can not open browse by using cmd.exe command
```
After commenting [these lines](https://github.com/iamcco/markdown-preview.nvim/blob/master/src/util/opener.ts#L14C1-L21C4) out, the plugin works again.
