Rule Change: Allow no-empty-blocks to ignore comment-only blocks

### What rule do you want to change?

no-empty-blocks

### What change do you want to make?

Generate fewer warnings

### How do you think the change should be implemented?

A new option

### Example code

```css
@media (min-width: 1200px) {
.sidebar { /* Fix this later */ }
}
```

### What does the rule currently do for this code?

The rule reports the block as empty.

The rule currently treats comments as not being content, so a block containing only a comment is reported. There is no option to change this behavior.

### What will the rule do after it's changed?

With a new option, users could choose for comment-only blocks to be treated as non-empty, so the example above would not be reported.

### Additional comments

This would bring `no-empty-blocks` closer to Stylelint’s `block-no-empty`, which does not report comment-only blocks by default: https://stylelint.io/user-guide/rules/block-no-empty/
