A11y: element should have child content with bind:textContent

[Glench]

Describe the bug
An A11y warning "element should have child content" is shown when an element has contenteditable="true" and bind:textContent={someVariable}.

To Reproduce
View the warning on this repl: https://svelte.dev/repl/26de97d4e85b4f30bd44f8859eacab8a?version=3.23.2

Expected behavior
There should be no warning since the element has content bound. I haven't tested with other parameters to see if the warning goes away.

Severity
Super low, but it helps not to get unneeded warnings in compilation. I'm hoping it's a super easy fix :)

Thanks so much for Svelte! I've been using it in a bunch of projects and I'm really loving it.

Yeah it probably makes sense for the Element#validate_content() method to ignore the element if it has a bind:textContent or bind:innerHTML.

Thanks for the ultrafast fix. Love this project
