Passing a value to a template parameter that is one of the dotnet new commands causes the cli to try and run that command instead

### Product

dotnet CLI (dotnet new)

### Describe The Bug

Consider you have a custom .net template which has a parameter of type string. If you try and pass a value to this parameter when running `dotnet new ` --myParam "my-value" where that value is also one of the dotnet new commands like (search, install, list, details etc) then the dotnet cli tries to run that command instead of executing the template.

### To Reproduce

Steps:
1. Create a new dotnet template with following folder structure and files.
```
/test-template
- /.template.config/
template.json
- /template/
ReadMe.md
```
2. Add the following to the `template.json` file under `.template.config` folder.

```json
{
"$schema": "http://json.schemastore.org/template",
"author": "Lewis",
"classifications": [ "Common", "Console" ],
"identity": "Lewis",
"name": "Test Template",
"shortName": "testtemplate",
"symbols": {
"customParameter": {
"type": "parameter",
"datatype": "string",
"defaultValue": "",
"replaces": "CustomParameterReplacement",
"description": "A custom parameter"
}
}
}
```

3. Add the following to the README.md file

```
Here is the value for CustomParameterReplacement
```

4. Install the template by calling `dotnet new install --force`

5. Execute the template by calling `dotnet new testtemplate --name test1 --output --force --customParameter "search"`

You get an error with the following output as it appears that the cli is trying to execute the `dotnet new search ` command instead.

This will also happen if you pass a string value matching any of the other `dotnet new` commands to the customParameter template parameter.

```
Unrecognized command or argument(s): 'testtemplate'.
Unrecognized command or argument(s): '--customParameter'.

### Visual Studio Version

_No response_

### Additional context

Interestingly, if you execute `dotnet new create ` instead then everything seems to work correctly and the template is executed. e.g. `dotnet new create testtemplate --name test1 --output --force --customParameter "search"`
