…lt in CI (#15463)

This is on platforms where the Mono SDK is supported.

When Mono JIT compiles `Main()`, it encounters a call to `new ConsoleRunner()`. Unlike CoreCLR, Mono JIT **attempts to resolve all field types of ConsoleRunner at JIT compilation time**, rather than deferring resolution until runtime.
The problem arises because some fields inside `ConsoleRunner` depend on **assemblies that are only resolvable via the assembly resolve event handler**. However, this resolve handler is **only installed after Main() has been compiled and execution starts**. As a result, Mono JIT fails when it attempts to load these types too early, leading to runtime errors.

This is a workaround for a limitation in Mono JIT by moving the instantiation to an another function.

Allow `Main()` to execute first**, ensuring that the assembly resolve handler is installed **before** `ConsoleRunner` is instantiated
