High values are not shown on download latency chart 📊.

[gorucci]

Describe the bug
High values are not shown on download latency chart. Some of my test results have high (pardon the repetition) "high download latency". To be specific, the 2 that are missing on a graph are 1006ms and 1102ms. This makes chart discontinuous.

To Reproduce
Steps to reproduce the behavior:

1. Somehow get a result with more than 1000ms (not sure for the exact value) high download latency.
2. Go to /admin aka Dashboard.
3. Scroll down to "Download Latency" chart.
4. See error.

Wow! That was crazy fast! Like, you know, off the charts fast (pun intended). Thank you.

TBH, I've tried to find a bug myself, like searching for the 1000 constant or analysing RecentDownloadLatencyChartWidget. But my lack of experience in PHP made this too tough 🥲. I had hope that your charts were made with some kind of JS lib.

number_format() function is what got us because it added a comma to the int which made it a string which the charts didn't like.
