Issue:
isPassport does not support new Canadian Passport Number Format
**Describe the bug**
The `isPassport` function does not support the new Canadian Passport Number format. 

Currently, `isPassport` only supports the old format of: 2 letters, followed by exactly 6 digits, represented by the regex (`/^[A-Z]{2}\d{6}$/`).

The new Canadian Passport Number format is:  1 letter, 6 numbers, and 2 letters.


**Examples**
[`src/lib/isPassportNumber.js` line 19](https://github.com/validatorjs/validator.js/blob/master/src/lib/isPassportNumber.js#L19)
` CA: /^[A-Z]{2}\d{6}$/, // CANADA`

This regex in English means: the string must start with exactly 2 uppercase letters from A-Z, followed by exactly 6 digits, and then the end of the string.

This could be fixed by modifying the existing regular expression to be: `CA: /^[A-Z]{2}\d{6}$|^[A-Z]\d{6}[A-Z]{2}$/, // CANADA`

**Reproductions**
If applicable, provide a reproduction on platforms like [runkit](npm.runkit.com/validator)

**Additional context**
Validator.js version: 13.12.0
Node.js version: any
OS platform: any
