Regenerating yaml and md5sum txt files

[Santhi1901]

The md5sum txt and yaml files need to be regenerated for the following GCSTs. The sumstats for these GCSTs have been updated as the user requested, and the metadata has not been changed. GCST90308719 GCST90319473 GCST90319474 GCST90319475 GCST90319476 GCST90319477 GCST90319478 GCST90319479 GCST90319480 GCST90319481 GCST90319482 GCST90319483 GCST90319484 GCST90319485 GCST90319486
