### What you expected to see, versus what you actually saw

What happens:
I have my white space settings set to Spaces, 4 Spaces Width and enforce this through an .editorconfig file in the root.
When Dependabot starts updating and filling a PR it rewrites all the white spaces in the file to match Spaces, 2 Spaces Width. This behavior creates conflicts each time when I pull the repo through GitHub Desktop / Visual Studio 2022.

What I expect to happen:
Dependabot respects the existing white space on the files and does not modify it.
Maybe even with a configuration switch to let the user decide which indentation is wanted?

### Native package manager behavior

An example where it just rewrites the whole file:

### Smallest manifest that reproduces the issue

_No response_

Start with the linked AzzyBot pull request #283, the repository’s .github/dependabot.yml, and its root .editorconfig, comparing the whitespace-only diff with the configured indentation. Then trace the GitHub Actions update path in Dependabot core; done means the formatting behavior is reproduced and a focused behavior or configuration decision is documented and covered.
