zsh autocompletions script emits invalid option switches

### Describe the bug

The zsh autocompletions script obtained from `dotnet completions script zsh` emits invalid option switches that contain slashes (e.g. `/v`), causing completions to fail and an error to fire for all attempted subcommand path completions.

### Steps to reproduce

In a new zsh session, run:
```shell
autoload -Uz compinit; compinit; eval "$(dotnet completions script zsh)"
```
Type the following and press TAB:
```shell
dotnet build ..
```

### Expected behavior

Path autocompletions should function properly and should not print an error to the command line.

### Actual behavior

The path completion fails, and the following error is printed to the command line:
```
_arguments:comparguments:327: invalid argument: /v=[Set the MSBuild verbosity level. Allowed values are q\[uiet\], m\[inimal\], n\[ormal\], d\[etailed\], and diag\[nostic\].]:LEVEL:((d\:"d" detailed\:"detailed" diag\:"diag" diagnostic\:"diagnostic" m\:"m" minimal\:"minimal" n\:"n" normal\:"normal" q\:"q" quiet\:"quiet" ))
```

### Is this a regression?

Same behavior on version 10.0.109, so not that I am aware of.

### Are there any workarounds?

None I know currently. I will update this issue when I find one.
