…bitrary properties work (#11039)

* ensure that last `]` doesn't stop the match

Given this input:
```html
<div class="[width:_calc(theme(spacing[5])_+_theme(spacing[5]))]"></div>
```

Then we would expect the match to be this:
```
[width:_calc(theme(spacing[5])_+_theme(spacing[5]))]
```

However, with the `?`, then it would stop and result in:
```
[width:_calc(theme(spacing[5])_+_theme(spacing[5]
```

Which makes it incomplete because the `))]` are missing at the end.

* update changelog
