feat: Configurable Doctrine SQL Column Length

[Crovitche-1623]

Using the form type supplied, the number is automatically converted to the E164 format. The E164 format has a maximum of 15 digits (without the "+"), so the length must be configurable, as the doctrine format is 35 characters long and hard-coded.

With my PR, it's now possible to configure the length of the column. For instance:

#[ORM\Column(type: PhoneNumberType::NAME, length: 16)]
private ?PhoneNumber $phoneNumber = null;

156
