Remove .JPEG & .PNG from extension list as .jpeg & .png are already present.

BUG
When a image folder has .jpeg or .png extension images. Imagelab loads that image twice as shown below,

Its happening because in src/cleanvision/utils/utils.py the extension lists have both '.JPEG' and '.jpeg', same for .png as well.

When loaded in the downstream code (by looping the extension list) using glob module to load the images, if a image has '.JPEG' extension, it load once for the '.JPEG' and once again for '.jpeg' because glob module treats both '.JPEG' and '.jpeg' as same image i.e, it doesn't matters if the extension is all caps or not.

Solution
Just keep '.jpeg' and '.png' in the list. It will handle even if the extension of the image is in all caps.

Thank you for pointing out this bug and contributing a bugfix! However the true root cause is the fact that glob is case-sensitive on Mac/Linux, but is case-insensitive on Windows.

We didn't do enough testing on Windows, but will start including Windows in our CI tests asap!
That said, this fix will not work since it will break things on Mac/Linux where glob is case-sensitive. Feel free to propose alternative fixes if you have thoughts, otherwise our team will be pushing a fix shortly.

Note the bug was just on Windows, so thanks a ton for pointing it out. Feel free to make other PRs if you see more opportunities for improvement!
