Downloading an attachment, appends a file extension. Even if original file didn't have one

[jr-m4]

Update: This is also present in the Windows Desktop Client. (tested with 2024.08.2)

Steps To Reproduce

In the browser web/interface (Edge):

1. Add an attachment that doesn't have an file extension e.g. ssh-keyfile or similar e.g "test-file"
2. Download this attachment "test-file"
3. Notice that the file downloaded is now called "test-file.txt"

Expected Result

The filename should be conservered, in this case without an extension. This is important when it comes to unix-based files, that often don't use file extensions. I.E in keyfiles and such.

Actual Result

File is renamed and now has an extension. In my example above it has now been given the extension .txt. Which on unix can lead to big issues if not aware!

I noticed on the Windows 11, latest, that the extension is added to files without extension: ->

Tried it now again. And the bug is still present.
