[BUG] all changes regardless of type are grouped incorrectly into modified_files in danger.git

[xphir]

Describe the bug

Since version 12.0.1, all changes (including deletions, creations, and modifications) are incorrectly grouped under modified_files. The created_files and deleted_files arrays remain empty, even when there are clearly file creations or deletions.

To Reproduce
Steps to reproduce the behavior:

1. On version 11.3.1, create a dangerfile.ts as follows:

import { danger} from "danger"

console.log("Created", danger.git.created_files)
console.log("Deleted", danger.git.deleted_files)
console.log("Modified", danger.git.modified_files)

2. Run the command npx danger pr https://github.com/danger/danger-js/pull/9.
3. Observe the expected output:

Starting Danger PR on danger/danger-js#9
Created [ 'yarn.lock' ]
Deleted [ 'npm-shrinkwrap.json' ]
Modified [ 'README.md', 'package.json' ]

Danger: ✓ passed review, received no feedback.

4. Update the version to 12.0.1
5. Run the same command: npx danger pr https://github.com/danger/danger-js/pull/9
6. Notice the unexpected and incorrect output:

Starting Danger PR on danger/danger-js#9
Created []
Deleted []
Modified [ 'README.md', 'npm-shrinkwrap.json', 'package.json', 'yarn.lock' ]

Danger: ✓ passed review, received no feedback.

Expected behavior
I would expect the behavior to remain consistent with version 11.3.1, where deletions are grouped in deleted_files, creations in created_files, etc.

Your Environment

software	version
danger.js	12.0.1, 12.1.0 & 12.2.0
node	v20.12.1 & v18.20.2

Yeah, I could believe that #1440 triggers this
