Old harmonised data missing yaml files

[jiyue1214]

There are some old studies in the format:
GCST123456

• *******.gz
• harmonised
  - GCST123456.f.tsv.gz
  - GCST123456.h.tsv.gz
  But missing the yaml file for harmonised data

Solutions: if the raw data did not start with the GCST, keep them as they are, generating a yaml file for the harmonised data.

There are 543 studies in the same situation: /nfs/production/keane/amp/AMP_harmonization/harmonization/test/no_yaml/check_files.txt
