Suggestions for improving gin-boilerplate

[mtskg]

As some of the current dependencies are outdated or no longer maintained, gin-boilerplate could benefit from some changes to existing setup. What do you think of making these changes to gin-boilerplate?

• Add OpenAPI 3.0 support through oapi-codegen for server code generation and documentation support.
• Replace go-gorp/gorp and pq with sqlc, pgx and use atlas for DB migrations.
  • gorp seems to no longer be maintained as no commits has been made since last year, and pgx is a better maintained alternative than pq these days.
