Discrepancy between `glGetInternalformat` documentation and `ARB_internalformat_query2` one

Hi! A discrepancy in OpenGL documentation was discovered:

The `glGetInternalformat` reference page says that it should return either `GL_TRUE` or `GL_FALSE` when queried for `GL_FRAMEBUFFER_BLEND`, but the `ARB_internalformat_query2` extension page says it should return either `GL_FULL_SUPPORT`, `GL_CAVEAT_SUPPORT`, or `GL_NONE`.

> If _pname_ is `GL_FRAMEBUFFER_BLEND`, _params_ is set to `GL_TRUE` to indicate that the internal format is supported for blending operations when attached to a framebuffer, and to `GL_FALSE` otherwise.
> -- https://registry.khronos.org/OpenGL-Refpages/gl4/html/glGetInternalformat.xhtml

> `FRAMEBUFFER_BLEND`: The support for rendering to the resource via framebuffer attachment when blending is enabled is returned in _params_. Possible values returned are `FULL_SUPPORT`, `CAVEAT_SUPPORT`, or `NONE`. If the resource is unsupported, `NONE` is returned.
> -- https://registry.khronos.org/OpenGL/extensions/ARB/ARB_internalformat_query2.txt

While `GL_FALSE` and `GL_NONE` are equal (`0`), `GL_FULL_SUPPORT` (`33463`) and `GL_TRUE` (`1`) are not.

Compare the glGetInternalformat reference page with the ARB_internalformat_query2 extension text linked in the issue, focusing on GL_FRAMEBUFFER_BLEND and its returned values. Reconcile the documentation so both sources describe the same valid results, then verify the affected generated reference content.
