feat: add ssl support using custom key/cert files

[dahifi]

Someone on the discord asked for a way to run the app behind https, so I added a run config parameters to accept keyfile and cert paths, and pass them to uvicorn.

I was unable to run commit hooks on this, nor did I test, but putting this here to see if anyone can validate or pick it up from here.

@dahifi if I add those changes to my local, I it will work? or is incomplete ? the added parameters must be provided as environment vars or running paremeters in chainlit executable ?

Best regards!

Thanks for your PR, there is a similar one here: #905

Do you have more background as to why folks who want to create a publicly accessible Chainlit instance without having a proxy in front of it?

[puppetm4st3r]

in my case the reverse proxy + chainlit + serving wasm artifacts didnt liked it to iOS devices, so I have solved appliying this PR and removing the nginx reverse proxy for serving the ssl and works fine.... and its a clearer solution for lite infrastructure use cases.

Looks good, could you add the CHAINLIT_ prefix to env variables?
I've tried to do it myself but I don't have the rights on your fork.
