Add support for react-number-format v5

[MartinSchmidt123]

During the first setup, react-number-format was installed with version 5.3.1.

Between v4 and v5 there are a few breaking changes and I run into

6: import NumberFormat from 'react-number-format';
          ^
[..]
error during build:
RollupError: "default" is not exported by "../../node_modules/.pnpm/react-number-format@5.3.1_react-dom@18.2.0_react@18.2.0/node_modules/react-number-format/dist/react-number-format.es.js", imported by "../../node_modules/.pnpm/react-hook-form-chakra-fields@0.1.7_@chakra-ui+icons@2.1.1_@chakra-ui+react@2.8.1_@emotion+re_kecz67imlc4dja4o5pzcfdqrli/node_modules/react-hook-form-chakra-fields/dist/react-hook-form-chakra-fields.esm.js".

This is also documented in the migration guide.

Downgrading react-number-format to version 4.9.4 solved the problem.
