OpenGL 4.6 missing

[sleepyspider1]

4.6 is nowhere to be found.
GetVertexArrayIndexediv for example does not show up and you can't query info about it.
But it does display the name if you start to search for it.

Isn't glGetVertexArrayIndexediv from OGL 4.5? And it's here, described along with glGetVertexArrayIndexed64iv: https://docs.gl/gl4/glGetVertexArrayIndexed

On the other hand, glMultiDrawElementsIndirectCount is missing.

I haven't been able to add support yet. Submissions welcome if anyone wants to take a stab.

glSpecializeShader is also missing
