We have a few places where even `GlTableLite` is too complex, or just inappropriate, but we want correct table styling by default. A solution would be to create a `GlTableSimple` component, much like `BTableSimple` from Bootstrap Vue (but [_not_ based on it](https://gitlab.com/gitlab-org/gitlab-ui/-/issues/2145)!), which pretty much just encapsulates the `<table>` element and applies a few classes.
