[Aftershock] Handle welding requirements via extend instead of overwriting vanilla

[Karol1223]

Summary

None

Purpose of change

On the devcord it's been reported that playing with both Aftershock and Magiclysm makes some of Magiclysm's stuff unusable for welding. This is because Aftershock overwrites the vanilla requirement group instead of extending it.

Describe the solution

Changed the syntax to be done through extending instead of ovewriting

Describe alternatives you've considered

Removing the marked as not-read copy-from lines for other extended requirements in that file, but it really isn't my business why they're there

Testing

Additional context

@John-Candlebury I'd like to make sure that this is an accepted approach. Aftershock had different values for vanilla tools, but I assumed that's because the Aftershock version wasn't updated since vanilla welding audits. If I am wrong in that assumption please let me know

Seems correct thanks Karol
