Bottom status bar (footer) does not responsively resize as viewport narrows

[cmsirbu]

Environment

• Nautobot version (Docker tag too if applicable): 2.1.4
• Python version: https://demo.nautobot.com/
• Database platform, version: https://demo.nautobot.com/
• Middleware(s): https://demo.nautobot.com/

Steps to Reproduce

1. Log in to https://demo.nautobot.com/
2. Resize browser window until status bar gets both horizontal and vertical scrollbars

It seems to happen when the width of the footer element reaches 1261 px. Both light and dark theme are affected.

Expected Behavior

The footer / status bar has plenty of padding available, so it should responsively resize as the viewport gets narrower without scrollbars showing.

Observed Behavior

A horizontal scrollbar appears, which in turn causes a vertical scrollbar to appear as well.

I believe a fix for this will be part of #5172.
