fix: send failure / skipped results to discord

[sapphi-red]

#388 made failure results and skipped results to be not sent to discord. This PR fixes that.

always() && condition seems to be the way to do this.

Probably this is how we can understand the behavior:

I would have expected the default value of if: success() to be replaced with if: <your_condition>, but it's actually if: success() && <your_condition> unless your condition includes one of the status functions
