Add Post Navigator setting for Blog Posts

[hgp22]

This feature implements an opt-in component that, when enabled, adds a navigator at the end of each blog post; so that the users are not forced to go back to the /blog page after reading each post.

It implements the feature mentioned in #118

Explanation for the Setting Placement

I decided to put this feature under params in the hugo.toml file, given that it is similar to hideMadeWithLine.

Implementation

The component in question follows the same strategies as the rest of the code:

• the new feature is in layouts/partials/post_navigator.html
• and it's implemented in layouts/partials/single.html

Final Note

I’ve added a summary of this feature in both the README.md and hugo.toml files. Additionally, I’ve included a brief explanation in the Development section to clarify how a developer should execute hugo commands from the root directory of this project.

I’m open to any changes or discussions.
