Don't rely on mtime to test changes #13143

Seems unrelated, but I wonder what it is 🤔

That seems weird but yeah, I'm not seeing how it could be related to this PR unless tests are tripping over each other (which they shouldn't be, obv). But I'm also not seeing it affecting other PRs. Maybe spurious? An access denied error can occur for a few different reasons, including permissions errors or if the directory exists and a delete is pending. But I'm not sure any apply to a temp dir. |

What does this PR try to resolve?
Fixes #13139 by making sure tests aren't relying on changing the mtime alone
How should we test and review this PR?
The pattern to watch out for is when a file is created with empty contents, e.g.
.file("foo", "")
, then later the same file updated with empty contents, e.g..change_file("foo", "")
. Tests should be making an actual change to the contents.
