Enable Funneling another port

[giomengu]

Hi all, not a Linux/Docker expert here (could be ignoring lots) but I was wandering if it was possible to enable selecting another port in the selection for funneling.
Possible use: I'm using home assistant cloud for accessing ha from my domain, don't really want to set up port forwarding just yet. Also having a Nextcloud instance running on ha, I would love to be able to funnel that to the internet and allow friends to reach the Nextcloud sever.

This is not part of the official add-on docs, and will never be, because this requires comand line access, but in my fork I wrote up the steps. Still in the dev branch even in my fork, but you can read it here: https://github.com/lmagyar/homeassistant-addon-tailscale/blob/dev/tailscale/DOCS.md#sharing-other-services-with-serve-or-funnel (note: when it talks about share_homeassistant option, that is an unmerged PR #445, where I merged the current proxy and serve config options into a single option, but you can use the "Steps" there)
