Snapshot: update pattern to avoid conflict

[meinaLi]

This script is basically no longer tested, but its pattern can affect new cases. Since the new cases are not recommended to update, I modified this one to avoide conflict.

Walkthrough

This pull request systematically renames the snapshot-related configuration keyword from snapshot_create to snapshot_creation across multiple entries in the resource abnormal test configuration file. The changes affect variant definitions for once_execute, twice_execute, leave_first options, and the top-level variants list. No structural or logical modifications are introduced.

The old cases pattern which are not expected to get resource.abnormal ones:

# avocado list --vt-type libvirt | grep snapshot_create | grep -v snapshot_create_as
avocado-vt type_specific.io-github-autotest-libvirt.snapshot_create.manual_snapshot.one_manual_snapshot
avocado-vt type_specific.io-github-autotest-libvirt.snapshot_create.manual_snapshot.three_manual_snapshots
avocado-vt type_specific.io-github-autotest-libvirt.resource_abnormal.snapshot_create.normal_resource.twice_execute.kill_first
avocado-vt type_specific.io-github-autotest-libvirt.resource_abnormal.snapshot_create.memory_lack
avocado-vt type_specific.io-github-autotest-libvirt.resource_abnormal.snapshot_create.cpu_busy

After fix, we can only get snapshot_create cases which can be directly used in snapshot auto job:

# avocado list --vt-type libvirt | grep snapshot_create | grep -v snapshot_create_as
avocado-vt type_specific.io-github-autotest-libvirt.snapshot_create.manual_snapshot.one_manual_snapshot
avocado-vt type_specific.io-github-autotest-libvirt.snapshot_create.manual_snapshot.three_manual_snapshots
