Example: ` # Apply Hasura GraphQL engine metadata present in metadata.[yaml|json] file:
hasura metadata apply
# Use with admin secret:
hasura metadata apply --admin-secret "<admin-secret>"
# Apply metadata to an instance specified by the flag:
hasura metadata apply --endpoint "<endpoint>"
# Prevent inconsistent metadata from getting applied:
hasura metadata apply --disallow-inconsistent-metadata`,
