[BUG] Importing DBML files doesn't preserve Ref keys(names)

[jamhour1g]

Describe the bug
I'm trying to import a DBML file where the refs are as follows:

Table users [headercolor: #175e7a] {
	id uuid [pk, default: `uuidv7()`]
}

Table user_sessions [headercolor: #175e7a] {
	id uuid [pk, default: `uuidv7()`]
	user_id uuid [not null]
}

Table addresses [headercolor: #175e7a] {
	id uuid [pk, default: `uuidv7()`]
	user_id uuid [not null]
}

Ref user_has_many_sessions {
	user_sessions.user_id > users.id [delete: cascade, update: no action]
}

Ref user_has_many_addresses {
	addresses.user_id > users.id [delete: cascade, update: no action]
}

or this:

Table users [headercolor: #175e7a] {
	id uuid [pk, default: `uuidv7()`]
}

Table user_sessions [headercolor: #175e7a] {
	id uuid [pk, default: `uuidv7()`]
	user_id uuid [not null]
}

Table addresses [headercolor: #175e7a] {
	id uuid [pk, default: `uuidv7()`]
	user_id uuid [not null]
}

Ref "user has many sessions" {
	user_sessions.user_id > users.id [delete: cascade, update: no action]
}

Ref "user has many addresses" {
	addresses.user_id > users.id [delete: cascade, update: no action]
}

To Reproduce
Steps to reproduce the behavior:

1. Go to 'File'
2. Click on 'Import from'
3. Select 'DBML'
4. Select the file

Expected behavior
I expect the tables to be drawn and the relationships name(key) to be persevered not overwritten with the default format of "fk_$foreignTableName_$foreignTableColumnName_$PrimaryTableName"
