Imrove docs for p5.Image.filter()

[aferriss]

Most appropriate sub-area of p5.js?

• Color
• Core/Environment/Rendering
• Data
• Dom
• Events
• Image
• IO
• Math
• Typography
• Utilities
• WebGL
• Documentation

Feature enhancement details:

I noticed that the docs page for filtering p5.Images is pretty scant on details of the individual filters with their parameters. It also suggests that users go looking for filters.js which seems like it could be tricky for beginners to locate. At least for me, the image.filter() page comes up first in the list on the reference search bar so unless you already know that there are two filter (three if you include sound) functions it could be hard to find.

I think it would be good to change it so that it is more in line with the main filter page. I feel like the docs on this page would be sufficient to move over to the image.filter() page along with some language about how that function only filters the image rather than the entire canvas.
Hopefully this would help newcomers find what they're looking for more easily.

This issue seems to be the duplicate of #5045 which has already been resolved by #5052.
