Describe the bug

When packaging a Fyne app I cam across an issue where I had the application name in the FyneApp.toml containing an ampersand:

[Details]
  Icon = "logo.png"
  Name = "App With & In Name"
  ID = "com.example.app-with-ampersand-in-name"
  Version = "1.1.0"
  Build = 1

This resulted in an error The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail similar to #1521

After reviewing the Windows Event Log there were entries showing Error in manifest or policy file "C:\path\to\app.exe" on line 2. Invalid Xml syntax

After replacing the & with and the issue went away.

I would assume the name is not being properly escaped in the generated manifest as an ampersand must be escaped as & in XML.

How to reproduce

1. Create FyneApp.toml with Name containing and ampersand character
2. Package using fyne package -os windows
3. Attempt to run app
