Based on the Go version we currently use, the dependency already supports 1.24+, which allows using `t.Context()` and `b.Context()` in unit tests and benchmarks respectively. - Enable `context-background` and `context-todo` in [`usetesting`](https://golangci-lint.run/docs/linters/configuration/#usetesting) - Adjust the code to support linter detection --------- Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> Co-authored-by: Tyler Yahn <codingalias@gmail.com> Co-authored-by: Damien Mathieu <42@dmathieu.com>
