jsonSerialize return type change warning

Bug Description

Getting PHP deprecation warnings due to a change of return type. Return type of JackSleight\StatamicBardTexstyle\TypeManager::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /vendor/jacksleight/statamic-bard-texstyle/src/TypeManager.php on line 503

Adding #[\ReturnTypeWillChange] or setting a return type on the method will silence this.

    public function jsonSerialize(): array
    {
        return $this->types;
    }

    #[\ReturnTypeWillChange]
    public function jsonSerialize()
    {
        return $this->types;
    }

How to Reproduce

Install addon, run any code.
