[Bug]: Tooltip max-width overrides --mod variable

### Code of conduct

- [x] I agree to follow this project's code of conduct.

### Impacted component(s)

tooltip

### Library version

1.7.0

### Expected behavior

Tooltips should respect the mod variable `--mod-tooltip-max-inline-size` custom property when defined, allowing consumers to override the default spectrum tooltip max width.

### Actual behavior

The `max-width` property in `packages/tooltip/src/tooltip.css` was overriding the `--mod-tooltip-max-inline-size` variable, preventing custom max-width values from being applied.

### Screenshots

### What browsers are you seeing the problem in?

### How can we reproduce this issue?
