Replace the deprecated Hugo variable
Replace the deprecated Hugo variable

## Problem

`Page.Hugo` variable was already deprecated. Hugo gave warning `Page.Hugo is deprecated and will be removed in a future release. Use the global hugo function.` when it ran every time.

## Solution

Replace `.Hugo` with `hugo` as the message suggested. Also see https://gohugo.io/variables/hugo/#readout for details.
