[Bug]: Default values on select controls aren't keep as defined

[SalahAdDin]

Describe the bug

So we defined the following configuration:

mport { Chip, CHIP_COLORS, CHIP_VARIANTS } from "./Chip";

const meta: Meta<typeof Chip> = {
  component: Chip,
  argTypes: {
    color: {
      options: CHIP_COLORS,
      control: "select",
      defaultValue: "neutral",
    },
    variant: {
      options: CHIP_VARIANTS,
      control: "select",
      defaultValue: "filled",
    },
  },
};

export default meta;

type Story = StoryObj<typeof Chip>;

export const Simple: Story = {
  args: {
    label: faker.lorem.word(),
  },
};

export const Label: Story = {
  args: {
    label: <LiveLabel />,
  },
};

export const Link: Story = {
  args: {
    label: faker.lorem.word(),
    to: faker.internet.url(),
  },
};

with:

export const CHIP_COLORS = [
  "error",
  "info",
  "neutral",
  "success",
  "warning",
] as const;

export const CHIP_VARIANTS = ["filled", "outlined"] as const;

We expect to see neutral and filled as default values on the controls, but:

Hi @SalahAdDin, to set default value, you should be using args instead. Something like this:

const meta: Meta<typeof Chip> = {
  component: Chip,
  argTypes: {
    color: {
      options: CHIP_COLORS
    },
    variant: {
      options: CHIP_VARIANTS
    },
  },
  args: {
    color: 'neutral',
    variant: 'filled'
  }
};

What does SomeType<T> means here? Is it just a plain text?
