fix: $value is not parsed and replaced in error messages

[willin]

Description

v0.13.1

Minimal code-snippet showcasing the problem

import { MinLength, Matches, validateSync } from 'class-validator';

class Demo {
  @MinLength(10, {
    // here, $constraint1 will be replaced with "10", and $value with actual supplied value
    message: 'Title is too short. Minimal length is $constraint1 characters, but actual is $value'
  })
  @Matches(/^$/, {
    message: '$target, $property, $value, $constraint1'
  })
  name: string;

  constructor(obj: any) {
    Object.assign(this, obj);
  }
}

const demo = new Demo({
  name: true
});

console.log(
  validateSync(demo, {
    // dismissDefaultMessages: true
  })
);
console.log(Object.values(validateSync(demo)[0].constraints));

Expected behavior

$value should be parsed.

Actual behavior

[
  ValidationError {
    target: Demo { name: true },
    value: true,
    property: 'name',
    children: [],
    constraints: {
      matches: 'Demo, name, $value, /^$/',
      minLength: 'Title is too short. Minimal length is 10 characters, but actual is $value'
    }
  }
]
[
  'Demo, name, $value, /^$/',
  'Title is too short. Minimal length is 10 characters, but actual is $value'
]

Also experiencing this issue on a nested object validation if anyone has found a solution?

I was going crazy with this, until I discovered that the message can be used as a function.
All you have to do is to use the message as function, and then access to the value passed:

Here you can see an example.

Hope it's Help.

At the moment, I'm still trying to remove the prefix from error message can't
