Incorrect argument arity in `--help` usage for publish/build/restore

### Describe the bug

`--help` indicates incorrect arity for sdk commands like `build`, `publish`, `restore`. It shows that the commands take zero or more projects/solutions/files, when the commands themselves error out if provided with more than one.

### Steps to reproduce

1. Run `dotnet build --help`.
2. See usage line: `dotnet build [...] [options]`. Notice the elipsis indicating this can appear multiple times.
3. try running `dotnet build` with multiple projects, as it indicates is possible.
4. Get error message that clearly indicates only one project can be specified.

### Expected behavior

Either multiple projects work, or the usage appears cleary indicates a zero or one arity (`dotnet build [] [options]`).

### Actual behavior

Usage indicates zero to many due to having the elpsises, but the commands don't work when multiple projects are specified.

### Is this a regression?

Does not appear to be a regression, or at least not a recent one.

### Are there any workarounds?

Trivial workaround: ignore `--help`'s usage, and look at man pages or online documentation, which both seem correct to me.
