Sebastiaan van Stijn 58d9cdd2d9 vendor: github.com/sirupsen/logrus v1.10.1
Notable changes:

- Add bidirectional `log/slog` integration with a Logrus hook and `slog.Handler`.
- Add minimal, composable logging interfaces for individual log levels.
- Fix reentrant logging deadlocks and improve concurrency safety around formatters, hooks, and entries.
- Fix generic `Log`, `Logf`, `Logln`, and `LogFn` methods unexpectedly panicking at `PanicLevel`.
- Allow `Entry.Caller` to be set explicitly and preserved across derived entries.
- Improve `TextFormatter` performance and reduce allocations significantly.
- Improve common Logger and Entry hot paths and caller-reporting performance.
- Update `TextFormatter` handling for `[]byte`, debug/trace colors, and Windows ANSI terminals.
- Raise the minimum supported Go version to Go 1.23.
- Deprecate `Entry.HasCaller` and `MutexWrap`.

//
// Additional fields added with [WithField] or [WithFields] are available in
// [Entry.Data]. Format should return the formatted log entry as a byte slice,

// It's not exported because it's still using Data in an opinionated way. It's to
