* fix: restore @ts-expect-error for CacheProvider type mismatch PR #30140 removed these comments assuming they were stale now that the repo is on TypeScript 5. The comments were about the compiler version, but the actual incompatibility is between react-inlinesvg/provider's CacheProvider (typed to return a bare ReactNode) and this repo's pinned @types/react@18.0.26, which requires JSX components to return Element | null. ReactNode includes undefined, so the JSX usage fails type-checking. Verified yarn build completes successfully with this restored. Fixes #30170 * docs: explain the actual @ts-expect-error compatibility condition Per @coderabbitai review on #30171: the old wording ("remove when upgrading typescript to v5") was itself stale/misleading, since the incompatibility is with the pinned @types/react version, not the TypeScript compiler version. Documents the real condition instead.
