Adds the DET.ekt Skillchip, upgrading the detective's sense of taste. (#84469)

## About The Pull Request
Gives the Detective a roundstart skillchip which allows them to unlock
the hidden potential of their tastebuds. With this, they can identify
chemicals by taste, and even identify bloodtypes in the same way.
## Why It's Good For The Game

I've been watching a lot of detective stuff and I think it's really
funny how often they stick their fingers into random goo/blood and
taste/smell it.
The idea of a detective chugging a glass of unidentified liquid to
identify that there's a lethal chem mix in there is equally funny to me.
Imagine you're recovering from a mugging in the medbay and the detective
comes in, takes a blood sample from you, and downs it in one go.
## Changelog
🆑 Wallem
add: The detective now starts with the DET.ekt Skillchip, which allows
