chore: Bump version for release v10.0.3 (#867)

# Motivation

We want to release a patch version of the library. All commits since
`v10.0.2` are dependency bumps, e2e/CI test fixes, and internal
adaptations to dependency API changes (`marked` v18 renderer signature,
DOMPurify typing, Prettier reformat). There are no new features and no
breaking changes — no exported API was added, removed, or re-signatured
— so this is a patch.

# Changes

- Bump version `10.0.2` → `10.0.3` in `package.json` and
`package-lock.json`.

# Screenshots

N/A — version bump only.
