Well, apparently, this is an A record for api.github.com. This name resolves to a different IP around the globe. See https://www.whatsmydns.net/#A/api.github.com
The IP is detected as “clean” on VirusTotal: https://www.virustotal.com/gui/ip-address/140.82.121.5/detection , although apparently (probably not surprising as it is github) is also a favorite address for everything including malware.
Maybe you can ask in the keepassxc discussion forum on github.
