Fix SPDX headers in all files
I ran the `bin/console spdx --fix` with different strategies for
different files. For most of the core classes, since they've been
drastically rebuilt, I've run it with the `git-blame` strategy, for for
the `src/Validators`, in which the API changed completely but the logic
remains the same, I use the `git-log` strategy.

StartsWith

  • StartsWith(mixed $startValue)

Validates whether the input starts with a given value.

This validator is similar to Contains, but validates only if the value is at the beginning of the input.

For strings:

v::startsWith('lorem')->assert('lorem ipsum');
// Validation passes successfully

For arrays:

v::startsWith('lorem')->assert(['lorem', 'ipsum']);
// Validation passes successfully

Message template for this validator includes {{startValue}}.
