chore(linters): Bump golangci-lint to v1.59.1

[zak-pawel]

• golangci-lint bumped to v1.59.1
• Addressing numerous findings caused by updates in several linters:

plugins/inputs/cloudwatch/cloudwatch.go:461:3         unparam     (*CloudWatch).aggregateMetrics - result 0 (error) is always nil
plugins/inputs/dovecot/dovecot.go:123:90              unparam     gatherStats - result 0 (error) is always nil
plugins/inputs/http_response/http_response.go:296:28  nolintlint  directive `//nolint:nilerr // error is handled properly` is unused for linter "nilerr"
plugins/inputs/logparser/logparser.go:151:60          unparam     (*LogParserPlugin).tailNewfiles - result 0 (error) is always nil
plugins/inputs/net_response/net_response.go:125:28    nolintlint  directive `//nolint:nilerr // error encoded in result` is unused for linter "nilerr"
plugins/inputs/net_response/net_response.go:132:28    nolintlint  directive `//nolint:nilerr // error encoded in result` is unused for linter "nilerr"
plugins/inputs/net_response/net_response.go:153:28    nolintlint  directive `//nolint:nilerr // error encoded in result` is unused for linter "nilerr"
plugins/inputs/raindrops/raindrops.go:152:13          nolintlint  directive `//nolint:nilerr // nil returned on purpose` is unused for linter "nilerr"
plugins/inputs/sqlserver/sqlserver.go:513:25          unparam     (*SQLServer).getTokenProvider$1 - result 1 (error) is always nil

• Matching the configuration file to the example from https://github.com/golangci/golangci-lint/blob/master/.golangci.reference.yml.

I believe that errors from unit tests which appeared on CI are not related to changes in this PR
