ib: bump `docker/ib/README.rst`

For the new github image, a high-level look at its basic
features/usage/docs and prosing around our expected default usage with
the `piker.brokers.ib` backend.

+## Max Pain Calculation for Deribit Options
+
+This feature, which calculates the max pain point for options traded
+on the Deribit exchange using cryptofeed library.
+
+- Functions in the api module for fetching options data from Deribit.
+  [commit](https://pikers.dev/pikers/piker/commit/da55856dd2876291f55a06eb0561438a912d8241)
+
+- Compute the max pain point based on open interest data using
+  deribit's api.
+  [commit](https://pikers.dev/pikers/piker/commit/0d9d6e15ba0edeb662ec97f7599dd66af3046b94)
+
+### How to test it?
+
+**Before start:** in order to get this working with `uv`,  you
+**must** use my [`tractor` fork](https://pikers.dev/ntorres/tractor/src/branch/aio_abandons)
+and this branch: `aio_abandons`, the reason is that I cherry-pick the
+`uv_migration` that guille made, for some reason that a didn't dive
+into, in my system y need tractor using `uv` too. quite hacky
+I guess.
+
+1. `uv lock`
+
+2. `uv run --no-dev python examples/max_pain.py`
+
+3. A message should be display, enter one of the expiration date
+   available.
+
+4. The script should be up and running.
