Describe The Bug

Given the template sources configuration for a custom template below:

....
"sources": [
    {
      "include": [],
      "modifiers": [
        {
          "condition": "(!someBoolParam)",
          "include": [
            "**/*"
          ],
          "exclude": [
            ".fake/**",
            ".paket/**",
            "paket-files/**",
            "..."
          ]
        },
        {
          "condition": "(someBoolParam)",
          "include": [
            "src/Folder/SubFolder/**/*"
          ],
          "exclude": ["Dockerfile"]
        }
      ]
    }
  ]
....

And Given the fact that the directory was already initiated from the template (someBoolParam == false)
When the dotnet new is executed in the existing directory where someBoolParam == true,
Then the "include" condition (i.e. "src/Folder/SubFolder/**/*") is ignored and all files in the directory are getting updated except for the excluded file (i.e. "Dockerfile"). Note: "exclude" was added to the example below just to show that "exclude" is working, but "include" is not. If "exclude" is removed, the "include" still does not work.

An example of the warning message displayed in the console:

Creating this template will make changes to existing files:
  Overwrite   ./.dockerignore
  Overwrite   ./.editorconfig
  Overwrite   ./.gitattributes
  Overwrite   ./.gitignore
  .............................................
  To create the template anyway, run the command with '--force' option:
  ............................................

Such template config worked as expected when using .NET 6 SDK, but after the update to .NET 8, the issue described above is started to appear.

To Reproduce

Steps:

1. Configure the template using sources from the description
2. Install template
3. Create a service from a template with someBoolParam set to false
4. Create a service from the template again with someBoolParam set to true
