git-artifacts: also build the UCRT64 flavor

Git for Windows is gaining a UCRT64 flavor, and I want the
`/git-artifacts` command (as well as the snapshot builds that cascade
from a `tag-git` run) to build those bits alongside the existing
x86_64, i686 and aarch64 ones.

The actual build logic lives in two other repositories: build-extra
learns to assemble installers, portable Gits and the like from a UCRT64
SDK (git-for-windows/build-extra#719), and the
git-artifacts pipeline gains `ucrt64` as a valid `architecture` choice
(git-for-windows/git-for-windows-automation#179).
This helper is what dispatches those pipeline runs, so once those two
pull requests are merged it needs to start asking for the fourth
architecture, too.

`triggerGitArtifactsRuns()` is the single place both entry points funnel
through: the `/git-artifacts` slash command when a `tag-git` run already
succeeded, and the automatic cascade when a `tag-git` check-run
completes. Adding `ucrt64` to its architecture list therefore covers
both without touching anything else.

I deliberately leave the `upload-snapshot` cascade and the `/release`
command at the three established architectures for now, so the UCRT64
bits are built but not yet published anywhere. A completing
`git-artifacts-ucrt64` check-run does still trigger the cascade handler,
because that handler matches on the `git-artifacts-` name prefix, but it
only ever looks up and forwards the three standard architectures' run
IDs. The extra completion is therefore harmless and, conveniently, a
failing UCRT64 build will not hold back the snapshot of the other three.
