webgl feature renamed to webgl2

[sebosp]

Addresses:

$ cargo build --release --example lighting --target wasm32-unknown-unknown --features webgl
error: none of the selected packages contains these features: webgl, did you mean: webgl2, webp?

Objective

• When following the instructions for the web examples.
• Document clearly the generated file ./target/wasm_example.js, since it didn't appear on git grep (missing extension)

Solution

• Follow the feature rename on the docs.

I don't think it's necessary to specify the feature at all, actually. webgl2 is a default feature.

Interestingly enough, the bevy_pbr feature is still called webgl. It's just that bevy_internal re-exports it as webgl2...

Removed the --features webgl2 since as you mention it's not default. Or would you prefer to have it another way?

In Bevy, the internal feature is kept as webgl as that's the name of the wgpu feature. But the external feature is webgl2 as I don't think it would work with WebGL1.
