Blender Version

Broken:
3.0

Short description of error
When exporting glft file, material's Bump texture is not converted into normal map, it just set Bump texture as normal map, which won't work well.

Solution
Need to convert Bump texture into a new normal texture when exporting gltf.

Or, add an extension standard for bump map to gltf's repo as a "Vendor", like these:
https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Vendor
