Describe the bug

When typing [[ the auto-completion is correctly triggered, but the candidates can't be searched/filtered.

For example, here is the list for my notes

But when I type h (or H), the candidates are just all gone.

Expected Behavior
The list of candidates should be filtered correctly and show the HHKB as the candidate.

How to reproduce?

1. In a folder of markdown notes
2. run zk init with the latest zk installed via homebrew
3. in neovim, type [[ to trigger the auto-completion

zk configuration

all default settings

Neovim configuration

{
        "mickael-menu/zk-nvim",
        config = function()
            require("zk").setup({
                picker = "telescope",
            })
        end
    },

### Environment

```bash
zk 0.14.0
system: Darwin 22.5.0 arm64
NVIM v0.9.0-dev-2556+g2dfb51a2b-Homebrew

@lazywei you haven't included the lsp setup entries in your config. Look again at the readme for the full base config.
