Update golangci-lint to v2.6.0 (#35801)

https://github.com/golangci/golangci-lint/releases/tag/v2.6.0

- `modernize` linter is enabled, this is the same as `gopls modernize`
- ~~`perfsprint` linter is disabled because it conflicts with
`modernize` (maybe there is a middle ground)~~
- gocritic `deprecatedComment` is disabled as it conflicts with
`go-swagger`
