Allow to pass table to config.window.border

[soifou]

Make sure you have done the following

• I have updated to the latest version of blink.cmp
• I have read the README

Bug Description

vim.api.nvim_open_win can accept a string or a table for border. See :h nvim_open_win.

However, it is no more possible to pass a table for window.border config in menu, documentation and signature.
The validation expects only a string and crash if a table is set.

Relevant configuration

signature = {
            window = {
                border = { '🭽', '▔', '🭾', '▕', '🭿', '▁', '🭼', '▏' }
            },
        },

neovim version

v0.11.0-dev+g203e7a43d1

blink.cmp version: branch, tag, or commit

main
