feat: require Next.js 15.1 and React 19 (#305)

7.10.0 release:
- updates and fixes the internal framework error handling detection, for
Next.js errors that have to be rethrown
- requires action callbacks and validation error shaper functions to be
async (see
[this](vercel/next.js#72336 (comment))).

The minimum required Next.js version will be stable 15.1 and minimum
React version will be 19. Older framework versions will not work with
next-safe-action >= 7.10.0, and vice versa.
