use COLORTERM=truecolor to get textual colors working via ssh

This is just a note for anyone else confused, but I set some custom RGB colors via textual, and it worked beautifully locally, but wasn't using the correct colors whenever I used the same textual app via SSH.

Example screenshots:

the colors in a textual app locally

the colors in a textual app via SSH before below env var updates

I normally set the following in my .bashrc everywhere (both on my local machine and the remote machine):

unset TERM
export TERM=xterm-256color

but that wasn't enough to make the textual app use the full spectrum of colors it was displaying locally, but then I found the following env var to set via my .bashrc on the remote machine:

export COLORTERM=truecolor

Now the same colors work both locally and via ssh :) I couldn't find anyone mentioning this via the discussions in the past. Hope this helps anyone else confused.

That's right. The COLORTERM env var will give you a full 16.7 million colors.
