fix: alignment of images of contributors

[AemieJ]

What's changed, or what was fixed?

• The alignment of the images along with the short brief description of the contributors wasn't aligned within the shorter screen width.

Fixes and aligns the images:

• This has been reviewed and approved by (NAME)
• I have run npm test locally and all tests pass.
• I have added the appropriate type-something label.
• I've staged the site and manually verified that my content displays correctly.
