[doc] add flowdapt integration to doc ecosystem page

[robcaulk]

Following a discussion in the slack channel with @richardliaw, we are adding Flowdapt to the ecosystem page since it offers a robust workflow configuring/scheduling/triggering interface to Ray.

Some background on Flowdapt:
Over at Emergent Methods, we depend on Flowdapt for production workflow deployment for our product https://asknews.app. Meanwhile, we have a variety of other integrations such as Nowcast, which is designed to adaptively retrain/inference weather forecasting models on thousands of cities simultaneously. Some of our clients depend on Flowdapt for QAQC for high-throughput data analysis.

One cool feature of Flowdapt is that we designed it to accommodate a variety of backends, including Ray and Dask, as well as a local executor. Swapping between backends requires zero-code changes for the application - which allowed us to run a big apples-to-apples comparison of Ray vs Dask: https://docs.flowdapt.ai/examples/rayvsdask/. Spoiler alert: Ray wins.

Some open-source example plugins available that run on Flowdapt (and are best run with the Ray backend):

Weather forecasting:

Cryptocurrency price forecasting:

Why are these changes needed?
