Updating Translations for "Next" and "Prev" Buttons

[adityatelange]

Hello All,

About the below translated strings:

hugo-PaperMod/i18n/en.yaml

Lines 1 to 5 in 1d2ecfe

	- id: prev_page
	translation: "Prev Page"
	- id: next_page
	translation: "Next Page"

Instead of mentioning: Next "Page", it would be better if we use only "Next" and "Previous" translations in place.
This issue was discussed in #235
