The "Subspace Bubble" advancement in the "Nether" section still uses the empty map icon

Actual behavior:

The "Subspace Bubble" advancement uses a regular, unexplored map icon. Meanwhile, the "Adventure" section and Adventure Mode use a buried treasure map icon.

Expected behavior:

The "Subspace Bubble" advancement is related to traveling and exploring the Nether. Similarly, the "Adventure" section is related to exploration and travel. The advancement should use the same icon as the "Adventure" section: a buried treasure map.

Alternatively, a normal opened map would be an even better choice, as it would more closely reflect the challenge associated with this advancement.

Required change:

Replace the current icon for the "Subspace Bubble" advancement with a buried treasure map icon or an opened map to better reflect the challenge of traveling and exploring the Nether.
