Update React to version 18 and other deps (#890)

This PR aims at updating some packages.
I'll keep this in draft until I'll be more happy with the results.
Current setup seems to work, I'll let the CI run and see how bad this
is.
Packages that needs to be updated/replaces:
- [x] ~autocompete - The only warning left in the console is related to
the autocomplete, which probably needs to be updated since it's a
package that wasn't updated in the last 6 years.~ #611
- [x] ~Codemirror is also something that will need an update, but it
looks too complicated at this point in time, so let's see how this
goes.~ #891
- [ ] react-color
- [x] ~react-aria-menubutton~ #846
- [ ] Others?

Most of the changes here are related to types, which is good.
