[BUG] Enum name generation throws error when including parenthesis ")"

[Verilyzed]

Describe the bug
When using brackets (parenthesis) in an enum name this error occurs.

What gets generated:

@JsonValue('Lieferbeginn (Einzug)')
lieferbeginnEinzug)('Lieferbeginn (Einzug)'),
@JsonValue('Lieferende (Auszug)')
lieferendeAuszug)('Lieferende (Auszug)'),

To Reproduce
Create an enum like this:

"ZaehlerstandAblesegrund":
  {
    "type": "string",
    "enum":
      [
        "Schätzung",
        "Zwischenablesung",
        "Zählereinbau",
        "Lieferbeginn (Einzug)",
        "Lieferende (Auszug)",
        "Unbekannt",
      ],
  },

Expected behavior
I would expect a normal generated enum. What should get generated:

@JsonValue('Lieferbeginn (Einzug)')
lieferbeginnEinzug('Lieferbeginn (Einzug)'),
@JsonValue('Lieferende (Auszug)')
lieferendeAuszug('Lieferende (Auszug)'),
