fix: darling unexpected literal type error

[tvincent2]

Hello!

When updating my dependency of validator from 0.16.1 to 0.18.1, I got the following error:

error: Unexpected literal type `path`
   --> /home/tvincent/.cargo/registry/src/index.crates.io-6f17d22bba15001f/validator_derive-0.18.1/src/lib.rs:228:22
    |
228 | #[darling(and_then = ValidationData::validate)]
    |                      ^^^^^^^^^^^^^^

From darling's README, it looks like the path given to and_then should be within double quotes, and indeed it fixed my build issue.

This PR simply adds the missing double quotes.

Thanks for making and taking care of validator (and zola!).

Hm was it changed in a version or depend on a specific version of rust? It definitely worked for me

I tested this on rust stable (i.e. 1.77.2 currently).

I tried to narrow it down a bit and it stops working for me with validator 0.17.0. The only changes I see are the bump of validator version and the introduction of darling in validator_derive's dependencies.

CI failures are a bit weird?
