Non-existent entries in certain tags that are not required causes validation error

      If a biome, structure, enchantment, or loot table tag is included in a data pack, which includes an entry with required set to false, and that biome/structure/enchantment/loot_table ID is not present in any data packs, the data pack fails to validate and the game tries to launch in Safe Mode. The output log produces this error (example with biome tag):

      And then lists the IDs that were listed, but are missing.

      Expected behavior is that if these IDs are not present among any loaded data packs, because they are not required, the game will ignore them for these tags and validate without them.

      Steps to recreate:

      1. Create a tag in <namespace>/tags/worldgen/biome
      2. Make this tag include at least one biome that does not exist, as an object with "required": false. For example, "test:test"
      3. Attempt to load the data pack in a world
      4. Observe that the game attempts to load the world in Safe Mode, and the output log has produced the above error.
      5. Perform the same test in 1.21.1 and note that the data pack validates as expected.

      Example tag for convenience:

      {
  "values": [
    "minecraft:plains",
    {
      "id": "test:test",
      "required": false
    }
  ]
}
