Add Support for React 19

[vessyb]

Hi ReactGrid Team,

Thank you for the great library—it has been an invaluable tool in my team's project. We are currently in the process of upgrading to React 19, but I’ve noticed that ReactGrid currently lists compatibility only with React 18 and earlier versions. I encounter dependency conflicts due to React 19 not being listed as a supported version.

Current Issue
Here's an example of the error encountered during installation:

Could not resolve dependency:
npm error Found: react@19.0.0
npm error node_modules/react
npm error   react@"^19.0.0" from the root project

npm error peer react@"^16.13.1 || ^17.0.0 || ^18.2.0" from @silevis/reactgrid@4.1.12
npm error node_modules/@silevis/reactgrid
npm error   @silevis/reactgrid@"^4.1.12" from the root project

This makes it difficult to integrate ReactGrid into React 19 projects without using workarounds such as --force or --legacy-peer-deps, which are not ideal.

Request
Could you please evaluate and add compatibility for React 19? If there are any known issues or blockers preventing ReactGrid from working with React 19, I’d appreciate it if you could share that information as well.

Additional Context
React Version: 19.0.0
ReactGrid Version: 4.1.12
Environment: Node 22.7.0, npm 10.8.2
Steps to Reproduce: Install ReactGrid in a project using React 19.

Thank you for your time and consideration.

Best regards,
Vesela

Hey guys, what is the progress on this topic? V5 is still in alpha, so it seems unreasonable to use in production, wdyt?
