Update plugin to Cake 4.x

[chrisShick]

I have done a little bit of tinkering and have all the existing tests passing. @ozee31 double check that this works as intended.

I think we also need this:

diff --git a/config/bootstrap.php b/config/bootstrap.php
index 203ff7d..e72638c 100644
--- a/config/bootstrap.php

Thank you. I'll test it within the week.

Also need to update AppExceptionRenderer. Here's updated diff on top @chrisShick's PR:
