[jest-dom/prefer-to-have-style] doesn't report when using `.toBe(variable)`

[StyleShit]

• eslint-plugin-jest-dom version: 5.5.0
• node version: 18.20.3
• npm version: 10.2.3

Relevant code or config:

// eslintrc.js
{
	// ...
	rules: {
		'jest-dom/prefer-to-have-style': 'error',
	}
}

// component.test.js

expect(node.style.color).toBe('red'); // Works

const red = 'red';
expect(node.style.color).toBe(red); // Doesn't work

What happened:

I'm referencing a variable in the toX() methods, but the rule doesn't report.
I would've expected it to report. Is it intentional? Didn't find other issues mentioning this, but the selectors in the code don't seem to handle it.
