Not compatible with RA 5

[Revarh]

Hi,

It seems the peer depencies for the project are locked on React-Admin 4.x

`"peerDependencies": {

"react-admin": "4.x"

},`

And in devDependencies:

"react-admin": "4.0.x",

It conflicts with installing RA 5 and thus the rest of the Enterprise modules.

Regards,

Marc
