[BUG] Activity "Open File" Logger Serialization Error

## Description
When reading a file from a Storage Provider with the "Open File" Activity from Elsa.FileStorage, with default Log Persistence, the workflow crashes silently.

## Steps to Reproduce
Configure Elsa.FileStorage to read from disk.
Create a Workflow that reads an existing file with the "Open File" activity.
Leave Log Persistence on Configuration or set it to Include.
Run the Workflow.

## Expected Behavior
The file is read and potentially stored in a variable set to "Memory" (because binaries can't be serialized)

## Actual Behavior
The Workflow will run, start reading and crash. The Instance Viewer usually shows all activities as "not executed" even if they ran before the "Open File" activity. The file the Instance tried to read cannot be deleted until the app is shut down, as it is marked as "being used by another process".

## Environment
- **Elsa Package Version**: 3.3.4
- **Operating System**: Win10/Win11.
- **Database**: MongoDB

## Log Output

## Workaround
The Workaround is to exclude the output of "Open File" from the Logs by setting the Log Persistence to exclude.
