Missing Quotes on timescale ports declaration

[waldren]

For me on macos 10.15.7, docker 20.10.2

timescaledb would not spin up. I got an http timeout error. I noticed the port was "" in the error.

I looked at docker-compose.yml and noticed that on line 9 the ports declaration were not quoted. I added quotes and this solved my issue. timescaledb spun up as did the web container.

Thanks for putting this together!

(P.S. - I also had to comment out torch in the requirements as stated in another issue)
