Issue:
[Bug]: class decorator context.kind is 'field', should 'class'
### 💻

- [ ] Would you like to work on a fix?

### How are you using Babel?

@rollup/plugin-babel

### Input code

```js
@DecTest
class Test {}

function DecTest(value, ctx) {
  console.log(ctx.kind, ctx, value);
}
```

### Configuration

```js
import { babel } from "@rollup/plugin-babel";

export default defineConfig(() => {
  const babelPlugins = [
    ["@babel/plugin-proposal-decorators", { version: "2023-05" }],
  ];

  return {
    build: {
      target: "es6",
      outDir: "./dist",
      emptyOutDir: true,
    },

    plugins: [
      babel({
        extensions: [".js", ".ts"],
        babelrc: false,
        configFile: false,
        compact: false,
        babelHelpers: "bundled",
        plugins: babelPlugins,
      }),
    ],
  };
});
```

### Current and expected behavior

context.kind should 'class'
