trigger_rebuild_pipeline: Update inputs to match ncov builds

[joverlee521]

The inputs required to trigger downstream ncov builds were originally set in Nov 2022 (80e5384).

The downstream ncov builds have since been updated to use different input files from S3 in April 2023:

1. use aligned.fasta instead of sequences.fasta
2. use zst instead of gz/xz files
3. 21L inputs were updated to aligned.fasta and zst files

This commit updates the inputs for the trigger rule to ensure that the downstream ncov builds are only triggered after the appropriate files have been uploaded to S3.

• Checks pass

Merging without review since the local dry runs are able to create DAG with updated inputs
