Make the 'Our Sponsors' section responsive

[mbvgua]

Add the css property overflow:hidden to the links in our sponsors section. This eliminates its overflowing that leads to displaying an empty giant chunk on the rightmost side of the website homepage when opened on smaller screens.

This is in reference to issue: #300

Managed to trace the bug to the 'Our Sponsors' section:

The red outline is where the image div is supposed to end, the words clearly overflow out of the div and into the other page contants. I rectified this by using a media query in the docs/.vuepress/styles/index.scss that changes display style from flex to block on smaller screens. This enables one to set the overflow property to hidden, and it will look like this:

Note

I used multiple sponsors to see how it will react to future changes, but it will work the same for a single sponsor.
The yellow outline is the links section and the red outline is a single image section

Thanks a ton for putting this PR together! Sorry it's taken some time to get to, it's a great find to get to the source of this issue.

We've actually just launched a full revamp of the website, which seems may have improved the responsiveness of this particular element.

Feel free to check it out to see if it solves what you've found, if it hasn't I'd be more than happy to help getting your changes into the codebase despite some of it's changes, just let me know
