docs(installation): i'm so sorry; fixes a mis-indented bracket

[cassiechew]

Description

There is a mis-indented bracket in the installation block.

-- lazy.nvim
{
  "folke/noice.nvim",
  event = "VeryLazy",
  opts = {
    -- add any options here
  },
  dependencies = {
    -- if you lazy-load any plugin below, make sure to add proper `module="..."` entries
    "MunifTanjim/nui.nvim",
    -- OPTIONAL:
    --   `nvim-notify` is only needed, if you want to use the notification view.
    --   If not available, we use `mini` as the fallback
    "rcarriga/nvim-notify",
    } <--- here
}

I've de-indented it by one.
