fix(vector): replace missing fonts BM-1091 (#991)

### Motivation

In both the `aerialhybrid.json` and `labels.json` stylesheets, the
`landfill` layer references an unsupported font.

### Modifications

For both stylesheets, I have updated the `landfill` layer's `text-font`
key-value pair:

| Before | After |
| - | - |
| `Roboto Condensed Italic` | `Roboto Light Italic` |

> Note: The `landfill` layer is also only one referencing the `Roboto
Condensed Italic` font.

### Verification

Before, tiles containing a `landfill` layer element would not render
because of the unsupported font.

| Before |
| - |
|

Now, such tiles render without issue.

| After |
