Update chai to v6 #13
Description
While updating deps I noticed that updating to chai v6 (currently 5.2.0) was not straight forward. I am leaving this here as I didn't have time to fix it this time so if anyone feel it can achieve it that would be great.
Please note that even ugrading to v5.3.3 (latest v5) is not working.
No major functionality impacted but at some point we will have to write the whole test suite again if too far behind.
