fix(create): stop forwarding -- to npx-invoked remote templates

`formatDlxCommand` injected `--` between the package name and its
args on the npx path, producing `npx <pkg> -- <args>`. Per the npm
v8 `npx` docs, the documented form places `--` before the package
name; the trailing `--` is forwarded to the underlying binary.
Commander-based subcommand CLIs (e.g., `@tanstack/cli create`)
interpret it as end-of-options and promote subsequent flags into
positionals, exceeding the subcommand's arity.

Drop the `--` injection for npx; pnpm/yarn/bun paths unchanged.
