What

Update arbitrum gas estimator settings:

refresh interval: 10s -> 2s
gas bump 1.5x -> 1.9x

Why

Basically, there's no higher bound on arbitrum's block-over-block base fee increases, so to deal with that better we shorten the refresh interval and increase the bump percentage.

….5x -> 1.75x

LGTM - It would be great if we can spin it up locally and test the behaviour just to be on the safe side.

LGTM - It would be great if we can spin it up locally and test the behaviour just to be on the safe side.

@dimriou Done! Below is the output, which shows that the base fee gets refreshed every 2s and is computed correctly:
