Update dependency @types/react to v17.0.43

Editor assessment

The subject names @types/react and states the destination version v17.0.43, which fully determines the change for any reader. The chore type and deps scope are accurate for a type-definition maintenance bump. No body is present and none is required, since a routine version bump carries no motivation beyond dependency upkeep; the absence is justified rather than a gap. No footers appear, so there is no noise and nothing malformed. Style is clean across the board: imperative phrasing, no trailing period, no ticket junk, sensible length, consistent language. The message communicates everything a reader needs in one line and misleads nowhere, meeting the standard for a maintenance commit.
