🛠 Changes

Added number in Tags for endpoints to adjust the alphabetical order.

ℹ️ Context for reviewers

I found that sorting endpoints in Swagger is not trivial task. We currently use alphabetical order:

# Sort order of endpoints by tags
springdoc.swagger-ui.tags-sorter=alpha
springdoc.swagger-ui.operations-sorter=alpha  

The numbers before the text in the endpoint tags will help us to change the order in the Swagger UI.

✅ Acceptance Validation
