        A list of enabled extensions.

        You should only use this option directly if the Telescope extension you wish to enable is not natively supported
        by nixvim.

        Most extensions are available as `plugins.telescope.extensions.<name>.enable`, although some plugins that do
        more than just provide Telescope extensions may use `plugins.<name>.enableTelescope` instead.

        If you add an extension to this list manually, it is your responsibility to ensure the relevant plugin is also
        added to `extraPlugins`.
