T2 repository: ask GitHub first, the Seoul host second

linux-t2, the kernel every x86 live ISO boots, comes from arch-mact2,
which has two servers in these configs: the maintainer's host in Seoul
and their GitHub release. Both carry the same database. An ISO build on a
runner in Virginia waited on the Seoul host at 0.45 MB/s for a 92 MB
package; the same file from GitHub came at 58 MB/s.

GitHub goes first, which is also the order of arch-mact2's own mirror
list. The Seoul host stays as the fallback.
