feat: add support to CONTAINS operations (#20)
This change adds a new operator `CONTAINS` that can be used to assert data by checking part of its content. When the `left` operand is a `string` it will compare if any part of the given string contains the given `right` operand. When the `left`operand is an `array` it will compare if any elements of the given array contains the given `right` operand.

| * Enum class for different operators. | ||

| * - EQUALS: Represents the equals operator (==). | ||
| * - NOT_EQUALS: Represents the not equals operator (!=). | ||
| * - GREATER_THAN: Represents the greater than operator (>). | ||
| * - GREATER_OR_EQUAL_THAN: Represents the greater than or equal to operator (>=). | ||

| * - LESS_OR_EQUAL_THAN: Represents the less than or equal to operator (<=). | ||
| * - STARTS_WITH: Represents the startsWith operation. | ||
| * - ENDS_WITH: Represents the endsWith operation. | ||
| * This enum class defines a set of operators that can be utilized in different contexts such as string comparison, | ||
| * numerical comparison, or array element verification. | ||
