Page's .Prev and .Next will be deprecated in a future Hugo release

[zwbetz-gh]

Hi there. My hugo version is 0.50. When building a test site with this theme, the console outputs the following deprecation warnings:

Building sites … WARNING: Page's .Prev is deprecated and will be removed in a future release. Use .NextPage (yes, not .PrevPage). WARNING: Page's .Next is deprecated and will be removed in a future release. Use .PrevPage (yes, not .NextPage).

Creating this issue as a friendly reminder.
