Update README to note that or, and and xor **do** short-circuit

[boris-petrov]

{{or true (throw "asd")}}

This, as of Ember 3.28, shows true. {{or false (throw "asd")}} throws an exception. So the section in the README which says that they do not short-circuit should be updated. It was true before, I remember, but it is no longer so.

😮 I see! I'm running Ember 4.12 (with ember-truth-helpers 3.1.1) and can confirm the now-short-circuiting behaviour

A more straightforward way to test this without needing the "throw" helper implemented

{{or true (log "OR - NOT CALLED")}}
{{or false (log "OR - CALLED")}}
{{and true (log "AND - CALLED")}}
{{and false (log "AND - NOT CALLED")}}

output

OR - CALLED
AND - CALLED

---

XOR still seems to call both though

{{xor true (log "XOR - TEST1")}}
{{xor false (log "XOR - TEST2")}}

output

XOR - TEST1
XOR - TEST2

makes sense, looking at the helper code
