[Refine] Think of new rules

[manuelarte]

Think of new rules that can be applied.

• do not include the default linters when using default: default and when default is missing https://golangci-lint.run/usage/linters/
• gci and goimports need to be together assets/formatters: update the GCI documentation golangci/golangci-lint#5891 fix: formats consistently the code with gci golangci/golangci-lint#5893

Also "suggestions" of configuration.
