bug(material): activated nav-list-item font color is not readable in dark mode

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

I have an App that uses a sidenav with a nav-list inside. I want the activated nav-list-item to be noticeable, so I'm using that state, but the default behavior with a dark theme, results in an unreadable font color.

### Reproduction

StackBlitz link: https://stackblitz.com/edit/components-issue-3qaoos
Steps to reproduce:
1. Open it.
2. See how the first nav list item is activated and barely readable.

### Expected Behavior

The background and font color have a minimum contrast, so the item is readable.

### Actual Behavior

The background and font color do not have a minimum contrast, so the item is not readable.

### Environment

- Angular: 16.1.0
- CDK/Material: 16.1.5
- Browser(s): Chrome 116.0.5845.97 (Official Build) (64-bit)
- Operating System (e.g. Windows, macOS, Ubuntu): Windows 11 (10.0.22621.2134)

Open the linked StackBlitz reproduction and inspect the Angular Material sidenav/nav-list behavior with the dark theme enabled. Verify the activated item’s foreground and background colors, then confirm the finished change meets the stated minimum contrast requirement in the reproduced scenario.
