Lebanese phone numbers are not correctly validated

[Mageek627]

Describe the bug
The isMobilePhone validator doesn't work for (at least some) Lebanese phone numbers.

Examples
With isMobilePhone('any', { strictMode: true }), this phone number: +96170072968 (which is the first example on https://en.wikipedia.org/wiki/Telephone_numbers_in_Lebanon) appears as invalid, but it's actually valid.

Possible solution
I would suggest using the google-libphonenumber library as dependency, as it seems to be very popular and very accurate for phone number validation.

Additional context
Validator.js version: 13.1.1
Node.js version: 14.8.0
OS platform: macOS 10.15.6
