Update preview-tui

[tax79]

Removed the color option from bat due to a bug while displaying any text files.

What "bug" are you talking about? It's best to elaborate if you make a PR.
The bug is more likely to be in your environment than in preview-tui.

If you can't be bothered to fix your environment, feel free to make these changes locally, no need to make a PR...

Try it yourself. lol
Now the preview looks like this:

If you change
--color=always
to
--color=auto
the problem is solved.

Like I said, the preview looks like that due to problems with your local environment.
sharkdp/bat#1113 sharkdp/bat#1063 seem related but those are supposed to have been fixed so I'm not sure.

In any case I use preview-tui every day and the problem is not present for me, I don't need to "try it myself", lol.

Changing 'most' with 'less' in this line solves the issue:
[ "$PAGER" = "most" ] && PAGER="less -R"
Now everything works as supposed to.
Thanks.

The fact that this is necessary for you must mean you have PAGER set in your environment without the -R flag. Adding that should be enough, see PAGER="${PAGER:-less -P?n -R}" in preview-tui.
