Issue when exporting resources with a slash/backslash in the filename

[paulandroshchuk]

• Laravel Version: 10.43.0
• Nova Version: 4.32.11
• PHP Version: 8.2.3

Description:

Noticed an issue with the CSV Export built-in action. When the name of the file has a slash or a backslash, it throws the following exception:

The filename and the fallback cannot contain the "/" and "\" characters.

If that's intended, could validation be added to that field at least? It just silently fails (no errors on the frontend, it just keeps the modal open) and you have no idea why until you manually find the error in laravel.log.

Detailed steps to reproduce the issue on a fresh Nova installation:

1. Create a Nova resource
2. Add CSVExport action to the resource
3. Try to export it with a slash/backslash in the filename
