fix(form): independence from validator broken

[ayoayco]

After implementing server-side rendered validation errors, the validator package was needed in form-control.ts

This breaks the independence of our packages.

Find a way such that validator is not a dependency of the form package: If the user did not install the validator package, then validation should simply be skipped. The question is, how do we dynamically import the validator package only if it is installed?

Also, I think It would be nice if we could show users a warning in the terminal if they used validators in their form control but forgot to install the validator package!
Something like:

"Warning: Install @astro-reactive/validator to work with validators"?

Good idea, though we should think about logging in another issue. Maybe create a logger in the common package.
