fix(golangci): remove warning abount deprecations

The configuration option `output.uniq-by-line` was deprecated, so
`issues.uniq-by-line` should be used. Beyond that,`output.format` is
also deprecated, and `output.formats` is the alternative. The linter
'exportloopref' since Go1.22 (loopvar) this linter is no longer
relevant. Replaced by copyloopvar.
