Pull request: test: deflake `test-repl-paste-big-data`

This test seems to be stable on CI but occasionally fails locally.

Running it alone in a loop gives me `user` times between `800_000` and `900_000` (which is dangerously close to `1e6`):

And when ran in parallel with other tests, it fails frequently.

This PR increases data length to lower fluctuations (x2 length takes about x3 cpu time here), increases the threshold, and moves the test to `pummel`.
