DOC: Clarify supported animation formats in animation tutorial

StefRe · StefRe · commit 89cd9e71f1e7 · 2022-11-24T15:47:11.000+01:00
- fix table to state the same as the text (ImageMagickWriter supports
  all formats supported by imagemagick) and add some examples
  (the extra args for apng are needed to reduce filesize by ~10x)
- add .webp as supported format to Pillow (since 2018 vers 5.0.0 )
- fix table formatting
