Update message when downloading logs

[mgreisen]

Information

• Onefuzz version: 8.8
• OS: n/a

Provide detailed reproduction steps (if any)

1. download the logs using the command "onefuzz debug logs get --job_id xxxx"

The statement that is returned to the console is: "INFO:onefuzz:Downloading only the 1 most recent files"

It is unclear that is the most recent file for each task.

Using alternate phrasing easily clears this up by adding "for each task" to the end.

There is no "most recent" anymore, since we should be downloading "all" logs by default

From what I understand, unless the --all flag is used only the --last n most recent logs are downloaded where n defaults to 1.

Edit: You're right about downloading "all" logs. In fact, it should be the only behavior rather than just the default behavior. See #3572.
