document that encoding/json omitzero/IsZero is not about assert.IsZero/reflect.Zero

[ccoVeille]

Description

The addition of omitzero to encoding/json creates confusion

Proposed solution

• Add information about this to the documentation of assert.Zero, or somewhere else more appropriate
• add a unit test with a simple struct that will implement IsZero() bool and return true to validate no changes is done in that direction

Use case

Prevent confusion and PR that might pop out

• feat: Use IsZero if types implement it #1704

I don't understand what should be added to the documentation. How are you confused?

If, as a maintainer, I don't understand the task to do, I don't expect an external contributor to understand better. So the labels good-first-issue and help-wanted are not appropriate.

Assigned to @ccoVeille : update the description to describe in depth your confusion. Or maybe just write the PR.
