Bumped @tryghost/logging to 4.1.0 (TryGhost#27541)

## Summary

Bumps `@tryghost/logging` from `2.5.5` to `4.1.0` across the three
places it's pinned:

- `ghost/core/package.json`
- `e2e/package.json`
- root `pnpm.overrides`

## Why

Catching Ghost up on `@tryghost/*` framework bumps. Logging is a leaf
dependency (dev/runtime tooling only, no public API surface exposed
through Ghost), so this is a low-blast-radius bump.

`@tryghost/logging` v3 and v4 are engine-floor bumps — they drop support
for Node 14/16/18 and modernize internals. Ghost's own `engines` already
requires Node 20+, so there's no runtime impact.
