Closes #2211

Proposed Changes

The arithmetic tables on the JMESPath page still described the behavior from before kyverno/kyverno#5544:

• add(): the table allowed mixing a number with a quantity or a duration, and a note said a number added to a duration counts as seconds. Both give a Types mismatch error now, so the table lists same-type inputs only and the note shows add('1h', '5s') instead.
• subtract(): two quantities give a quantity (subtract('1Gi', '512Mi') is 512Mi), not a number. The section's own example, 10Mi minus 5Ki giving 10235Ki, already says so.
• modulo(): two quantities or two durations work too (modulo('10Mi', '3Mi') is 1Mi), so they're added to the table.

I checked every row against Kyverno's JMESPath engine on main. The divide() and multiply() tables already match.

🔵 Needs a closer look

Update the add-demo fallback to a quantity-typed zero or another type-preserving fallback.

What changed in this PR

This documentation-only pull request updates the JMESPath arithmetic filter reference to reflect Kyverno’s current type-handling behavior.

Changes:

• Restricts add() to same-type operands and updates its example.
• Adds quantity and duration support to the modulo() table.
• Corrects quantity output for subtract().
• The add-demo example still uses a numeric fallback that can cause a type mismatch with quantities and should be updated.

@aerosouund the add-demo fallback that Copilot flagged works as written: the `0` sits inside the quoted variable, so add() gets the string '0' and parses it as a quantity (with the 1.19.2 CLI the policy passes a Pod that only sets requests.memory and denies one with 100Mi requests plus 150Mi limits). Would a sentence saying that quoted numbers parse as quantities help here, or is the same-type note enough?
