Typo / Capitalization in readme

[Presskopp]

Regarding the readme.txt file, there is a typo:

ng -> png:

WebP is definitively an excellent replacement for jpeg, png, and gif images, and the same goes for AVIF, which improves your image performance even further. Imagify offers WebP conversion for all image formats: you can convert gif to webP, jpeg to WebP, and even png to WebP. You can also benefit from AVIF conversion and convert gif to AVIF, jpg and jpeg to AVIF, ng to AVIF, and even WebP to AVIF!
Whatever your favorite image format, let Imagify optimise your images!

Also the capitalization of the formats (jpeg, gif...) is unclear (webp, WebP). If you ask me, they all should be capitalized.
