Documentation on expressions should be updated

[fireflysemantics]

In the documentation on expressions it says the following:

You might also want to remove the attribute if the value is not truthy so that values of false or empty string '' remove the attribute

Empty string '' is truthy. So an empty string will leave the attribute in place.

This is the demo snippet in the documentation.

html`<button aria-label="${this.ariaLabel || nothing}"></button>`

This will leave the attribute in place if ariaLabel=''.

Empty string is falsy and as such it the code snippet correctly falls back to nothing when using ||, therefore removing the attribute.
See this playground example. If you inspect the <p> element, foo attribute does not exist, but bar does.

I also do not see any attribute on the <button> element in the provided stackblitz example either.

@augustjk good catch .... I got my wires crossed ... :)
