fix(vector): update helipad icon-image symbol BM-1095

[tawera-manaena]

Motivation

As a Basemaps user, when I view the Aerial layer with labels enabled, I cannot identify helipad locations like I can when viewing the Topographic layer.

Sprite files

When we compare the Aeroway-Helipads layer of the topographic.json style to that of the labels.json style. We can see that the two styles reference different sprite files.

• topographic.json

  "icon-image": "helipad_pnt_fill"

  The helipad_pnt_fill sprite file exists within the sprites/topographic directory.

• labels.json

  "icon-image": {
    "stops": [
      [10, "heliport_11"],
      [15, "heliport_15"]
    ]
  }

  The heliport_11 and heliport_15 sprite files do not exist within the sprites/topographic directory.

Modifications

For both the aerialhybrid.json and labels.json styles, I have updated the icon-image property of the aeroway-Helipads layer to reference the same sprite file (helipad_pnt_fill) as the topographic.json style:

• aerialhybrid.json

  "icon-image": "helipad_pnt_fill"

• labels.json

  "icon-image": "helipad_pnt_fill"

Verification

Using the links provided by the github-actions bot, when I preview both the Aerial Hybrid style and the Labels style, I can now identify helipad locations, respectively.
