[Scitech] Package group: scitech_sig or scitech-sig?

[Jun Aruga]

It's a small thing.

Seeing the list of the package groups,
https://koschei.fedoraproject.org/groups

I noticed the package group name that means the SIG is "*-sig" except
scitech_sig ("*-sig").
Only "scitech_sig" is underscore.
Shall we change the group name from "scitech_sig" to "scitech-sig"?
