Add React 19 support

Is your feature request related to a problem? Please describe.

Please add React 19 support, as now I have to build the project using the --force flag

Describe the solution you'd like

I hope updating project.json will be enough

Describe alternatives you've considered

For now, I have to use the older React 18 or --force flag when building with v19

I forked it not long ago but have not been able to work on a fix. I've been busy painting my house and then I got some family visits over and have not opened my computer at all.

I will try to give it a go in the following 3-4 days.
