Fix image_loader for animated image types (#5688)
Hi, after upgrading to 0.31.0 all of my beautiful static webp images
started failing to load. I use the image_loader to load those via the
`image` crate.

I noticed that with 0.31.0 there are additions to how animated image
types are handled with frames and such. And with those changes the frame
index is attached to the uri at the end. This was problematic for the
image_loader, because it wasn't updated to handle that frame tag at the
end of the uri, so when looking up the bytes, it would fail to match the
uri in the bytes cache (the bytes were being saved without the frame
index, but attempting to be fetched _with_ the frame index).

This fixes the image_loader for me with webp & gif. They don't load the
animations, but I think that is because I don't have the custom
image_loader set up so I'm not worried about that for myself. I'm not
sure if that part is problematic in general, or if its just the way I
have my features set up.

You can recreate the issue on master by swapping out the dependency
features in the `images` example like this:
```
# egui_extras = { workspace = true, features = ["default", "all_loaders"] }
# env_logger = { version = "0.10", default-features = false, features = [
#   "auto-color",
#   "humantime",
# ] }
# image = { workspace = true, features = ["jpeg", "png"] }
egui_extras = { workspace = true, features = ["image", "svg"] }
env_logger = { version = "0.10", default-features = false, features = [
  "auto-color",
  "humantime",
] }
image = { workspace = true, features = ["jpeg", "png", "webp", "gif"] }
```

now converted to lowercase before comparing

Fix broken images on egui.rs (move from git lfs to normal git) (#5480)
The images in the widget gallery on egui.rs are broken:

![image](https://github.com/user-attachments/assets/305e1041-e3e3-472d-9a52-1b90e8da053d)

~Not sure why yet, and I fail to reproduce locally.~
It's because they are on git lfs.

I removed the webp supported URI test given that the webp feature would
have to be enabled. I kept that webp is not supported in the other
tests.

There might need to be an additional warning in the changelog that image
support detection is now stricter.

Related to #3482 

Not sure what the "best practice" is, to me it seems like one should
import from "the original location" if possible, but now it should at
least be possible to not re-export ahash without any breakage in the
egui code base (but possibly in projects using egui, so one should
probably deprecate it if one would like to go that path). It also seems
like epaint re-exports ahash.
