`InspectCode` calls the exe file even on Linux, where it doesn't work

### Prerequisites

- [X] I have written a descriptive issue title
- [X] I have searched [issues](https://github.com/cake-build/cake/issues) to ensure it has not already been reported

### Cake runner

Cake .NET Tool, Cake Frosting

### Cake version

4.0.0

### Operating system

Linux

### Operating system architecture

64-Bit

### CI Server

_No response_

### What are you seeing?

I would like to run `InspectCode` on my solution. I have installed the [ReSharper Command Line Tools](https://www.jetbrains.com/resharper/features/command-line.html), as they contain the same code as the NuGet package (but can be installed globally once). On Linux, they need a custom runtime, therefore should be started from `inspectcode.sh` and not `inspectcode.exe`.
Therefore, I get the error
```
Failed to fill the environment container with handler ?{myArgs=?(2pcs)[/output:/output.xml, solution.sln]?}?. Could not find method '.ctor' due to a type load error: Could not load file or assembly 'PresentationCore, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. assembly:/opt/resharper/JetBrains.Platform.Util.dll type:ListEvents`1 member:(null)
```

Unfortunately, `inspectcode.exe` is hardcoded in Cake. I would like to see a switch based on the current OS.

### What is expected?

If I run `InspectCode` on a Linux machine, `inspectcode.sh` is used instead of `inspectcode.exe`.

### Steps to Reproduce

Call `InspectCode` on a Linux machine

### Output log

See above for the error message

Start by locating the InspectCode entry point and the code that hardcodes inspectcode.exe. Reproduce the command on Linux, then verify the expected script is selected there and the existing executable remains selected elsewhere.
