It’s generally ok to create github issues; even trivial issues can be useful. I’m not active in the bazzite github, but I have contributed to a few open source projects. Personally, I wouldn’t find this sort of issue annoying.
When contributing to a project for the first time, I usually start with minor bugs and typos, just like this. They might seem trivial, but solving simple problems is the best way to learn how things fit together.
