Add a simple dockerfile to run i locally

[Saboti]

Hi, I added a simple dockerfile to build a image with you great Ollama chat client.
example docker build: docker build -t ollama-chats .
example docker run: docker run -d -p 4000:80 --name ollama-chats --restart always ollama-chats

thank you, i still hope that ollama team will listen to me and add native support for web based uis :). right now i'm in the middle of doing a new feature for UI and don't want to get distracted to install docker and test the script (i don't use docker). if ollama team won't do the native support, i will then figure this out and add to the project as an option for docker users. again, thank you for help and sorry that i'm so slow :).
