Display downloader jobs in console debug log

[cjjdespres]

The string for this particular log message (displaying the downloader jobs every 30s) was missing a $ before jobs, so the list of jobs was not being displayed in the console output.

I tested this change by syncing a node to devnet and observing that the downloader jobs were in fact printed. (I've omitted the full list to save space).

2025-10-01 18:26:28 UTC [Debug] Downloader $jobs
  jobs: {
  "total_jobs": 0,
  "useful_peers": {
    "all": {

Before this change, this line would just be this:

2025-10-01 18:26:28 UTC [Debug] Downloader jobs

I think you can workaround by forcing logs to be emitted as json.
