feat(react): add support for React 19 for new Workspaces

[Coly010]

Current Behavior

We currently have no support for React 19, generating only React 18 applications.

Expected Behavior

Add utils to determine what version of React is installed in the workspace.
If React 18 is the main version of react installed, continue to generate React 18 projects.
If React 19 is the main version of react installed, generate React 19 projects.
If no React version is installed or can be determined, generate React 19 projects.

@Coly010 how this affects Next apps?...

Blocked until Unit Testing solution is ready

[beaussan]

I see that this pr introduce a create graph async during a generator, this is already causing issues regarding eslint (see #27849), can we envision a generator parameter to explicitly say the version of react to expect?

Otherwise, every generator that are built on top of this will have their test and run go way slower due to creating a fresh graph

[gperdomor]

@Coly010 can you add vitest support to next app generator too? 🙏🏻
