fix: the `$value` placeholder is not replaced in validation error messages

[waji-io]

Description

When triggered a validation error, the resulting error message with the variable $value shows the variable name instead of the actual value. Other ValidationError variables still work, like $property or $contraint1

Minimal code-snippet showcasing the problem

@Max(250, { message: '$property is too big. Maximum value is $constraint1, but actual is $value' })
limit: number = 100;

Expected behavior

Show the actual value of $value and not its name.

Actual behavior

Instead of seeing the following validation error message:

"limit is too big. Maximum value is 250, but actual is 500"

I am seeing this:

"limit is too big. Maximum value is 250, but actual is $value"

Has anyone dug into this one and found the issue? I'm experiencing this on validating a nested object input type
