Support React 19

[PedroAVJ]

Describe the issue and the actual behavior

When upgrading next js to version 15 I get the following warnings after running their upgrade codemod

react-number-format 5.4.2
  ├── ✕ unmet peer react@"^0.14 || ^15.0.0 || ^16.0.0 || ^17.0.0 || ^18.0.0": found 19.0.0
  └── ✕ unmet peer react-dom@"^0.14 || ^15.0.0 || ^16.0.0 || ^17.0.0 || ^18.0.0": found 19.0.0

Describe the expected behavior

React 19 should be listed as peer deps

I'm also interested in making it compatible with React 19 to enable migration. It's the only dependency left to migrate.
