Subject: [PATCH] fix(statuscolumn): fix `folds_open = true` (#3756)

After some recent changes in https://github.com/neovim/neovim/pull/28709
I was getting an error when the user had `folds_open = true` in his
personal configuration whenever he pressed `o/O`. This is an attempt to
fix that.

## What is this PR for?

I was getting an error with `folds_open = true` in the user
configuration whenever pressing `o/O` or pressing `Enter` for a new
line.
The error was `Error executing lua:
...e/jrn23/projects/plugins/LazyVim/lua/lazyvim/util/ui.lua:127: attempt
to index a number value`.
