Removes duplicate reference of ARRAY_CUSTOM_RGBA8_UNORM

[akien-mga]

Looks good.

Looking at some of the code I think this should be ARRAY_CUSTOM_RGBA8_SNORM instead

Not sure if this is the code for this but this seems relevant:

godot/servers/rendering/renderer_rd/storage_rd/mesh_storage.cpp

Line 1298 in b4e2a24

const RD::DataFormat fmtrd[RS::ARRAY_CUSTOM_MAX] = { RD::DATA_FORMAT_R8G8B8A8_UNORM, RD::DATA_FORMAT_R8G8B8A8_SNORM, RD::DATA_FORMAT_R16G16_SFLOAT, RD::DATA_FORMAT_R16G16B16A16_SFLOAT, RD::DATA_FORMAT_R32_SFLOAT, RD::DATA_FORMAT_R32G32_SFLOAT, RD::DATA_FORMAT_R32G32B32_SFLOAT, RD::DATA_FORMAT_R32G32B32A32_SFLOAT };

Might need to be another constant, see comments.

Indeed, ArrayCustomFormat's docs already say it's one of the encoded as PackedByteArray formats:

godot/doc/classes/Mesh.xml

Lines 264 to 290 in 36e943b

Looks good now. Great work!

The last step before we merge this is for all the commits to be "squashed" into one commit. We like to have only one commit per PR to keep our git history clean. We have a really helpful tutorial on squashing your commits together in the docs https://docs.godotengine.org/en/latest/contributing/workflow/pr_workflow.html#the-interactive-rebase

The final result should be just one commit in the PR with a clear commit message

[AThousandShips]

Please edit your commit message to remove unnecessary messages from commits, should just say:

Remove duplicate reference of CUSTOM_ARRAY_RBGA8_URNOM in docs
