DEV: Use `concat-class` helper when setting class for `DButton` (#21998) 

Why this change?

Currently, we're interpolating within a string to set the class for the
`DButton` component. However, the interpolation and formatting of our
handlebars templates result in unnecessary spaces being added to the
class attribute.

```
<button class="sidebar-section-header sidebar-section-header-collapsable btn-flat

    btn
    no-text
    " aria-controls="sidebar-section-content-categories" aria-expanded="true" title="Toggle section" type="button">
  ...
</button>
```

This makes the HTML elements for buttons hard to read especially when
we're debugging issues in the console. After this change, this is what
we get:

```
<button class="sidebar-section-header sidebar-section-header-collapsable btn-flat btn no-text" aria-controls="sidebar-section-content-categories" aria-expanded="true" title="Toggle section" type="button">
   ...
</button>
```
