Add pagination to search results

Summary

Add pagination to search results

Details

Adds pagination to search results rather than only display the top 10 results.

Here are a couple of screenshots of how it'll look in light mode and dark mode. Please note that to easily test pagination here I simply copied the Features.md document 20 times and changed the filename, hence all the results are for features.

If there is only one page of search results, the pagination is not displayed

Not sure why that test is failing on Python 3.8, it works locally. Maybe a timing issue?

@kura Looks great! Nice implementation.

@Linbreux thanks.

I may make additional tweaks to the search system over the next few weeks too. I'm thinking about messing around with facets (something like allowing you to filter the results by sub directory) and stemming.
