Introduce Trimmed validator
This commit introduces the `Trimmed` validator that ensures a string
cannot start or end with a list of specific values.

The default values used are a selected list of Unicode invisible
characters.

To support this change, the StartsWith and EndsWith validators were
modified so they can also support multiple values to check for.

While StartsWith and EndsWith are more generic, and also perform
start-of-array and end-of-array kinds of checks, Trimmed is more
focused on string inputs, which tailors to a more specific use
case.

StartsWith

  • StartsWith(mixed $startValue)
  • StartsWith(mixed $startValue, mixed ...$startValues)

Validates whether the input starts with one of the given values.

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

v::startsWith('Dr.', 'Mr.')->assert('Dr. Jane Doe');
// Validation passes successfully

For arrays:

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

v::startsWith(0, 1)->assert([0, 1, 2, 3]);
// Validation passes successfully

v::startsWith(0, 1)->assert([1, 2, 3]);
// Validation passes successfully

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