PhoneNumber scalar is not fully compatible with E.164 format so updated regex to support phone number with extension

[nthombare-mdsol]

Description

Following recent discussions, it was determined that phone number support does not fully comply with E.164 standards. As a result, we also need to support phone extensions, which is addressed in this PR. Additionally, comprehensive test coverage has been added to cover all possible phone number formats.

The regex supports all phone numbers compliant with the E.164 international format standard, which includes country code (Optional), area codes, and local numbers and extension (optional). For more information on E.164 formatting,

Ex. +62 (21) 9175 5194, 2191755194, +1 123-456-7890 12345, +1 (123) 456-7890
