feat: add keybinding to open dashboard

[jara505]

Overview

Add a global keybinding to open the Wrapped dashboard without typing the :WrappedNvim command manually.

This change addresses the need for a more efficient workflow, as Neovim users typically prefer keyboard shortcuts over typing commands manually.

Key Changes

• Added <leader>gw as a global keybinding in plugin/wrapped.lua
• Updated README.md with the new mapping in the Mappings table

Impact

• plugin/wrapped.lua — Added keymap
• README.md — Documentation update

hello @jara505! really appreciate the PR

regarding the predefined keybindings: i think it's better practice to leave those entirely up to the user. neovim users usually have very specific setups, and hardcoded mappings (especially using <leader>) often clash with existing configs.

since wrapped already exposes its API via require("wrapped").run() and provides the :WrappedNvim command, users have everything they need to set up their own preferred shortcuts.

for example, they can map the lua API:

-- mapping it to a key 
vim.keymap.set("n", "<leader>gw", function()
    require("wrapped").run()
end, { desc = "run wrapped" })

or use a mapping that utilizes the command as you did in the PR.

instead, i think it would be more handy to add a "Recommended Keybindings" section to the README. this is especially important as i’m planning to add a new feature for calling wrapped on specific projects rather than just the neovim configuration, which is why keeping the keybindings flexible is important.
