Update phone number format validation across NGO HUB

[anastk-code4]

Currently, phone number fields allow only romanian phone number format.
We need to allow international phone number format.

See affected fields in Data Dictionary NGOHUB
NGOADMIN_PHONE
NGO_PHONE
NGO_REPPHONE
NGO_COUNCIL_PHONE
NGO_PPL_PHONE

Hello,
@anastk-code4 @mirunaioana-msc

I've created a PR regarding this issue, however, we'll keep a strict validation in the backend, while having a light one for the frontend.

The reasoning for this issue can also be found in the library that we use for the frontend validation:

Please confirm that this is alright.
The phone number is still strictly checked in the backend.
