**Description**

Set the `hookFunction` to pass our own `sign function` for customized signing.

Does the Windows installer support hookFunction? If not, is it possible to add support for it?

**Why is hookFunction needed**

In Electron Builder, many signing algorithms are implemented (for example, Azure Pipelines, or signing as part of a pipeline for other files to be signed). If `hookFunction` is supported, these signing functions can be directly passed through. However, if it's not supported, users would need to re-implement these functions themselves and pass them via `hookModulePath`. This places higher demands on the users and results in redundant implementation.
