WebGL2 support broken: index out of bounds

[DGriffin91]

Bevy version fe777d5

The deferred rendering example is broken on WebGL2 (And will also be broken on WebGPU, I expect).

The issue was introduced at 4c15dd0 with #10268

panicked at [...]\.cargo\registry\src\index.crates.io-6f17d22bba15001f\wgpu-hal-0.19.1\src\gles\command.rs:749:21:
index out of bounds: the len is 16 but the index is 16

[mockersf]

the error message is different with WebGPU, but it could be the same error with a more explicit log:

The number of sampled textures (17) in the Fragment stage exceeds the maximum per-stage limit (16).
 - While calling [Device].CreatePipelineLayout([PipelineLayoutDescriptor]).

This should be fixed by #11893 correct?

@alice-i-cecile No, this is a separate issue.
