generated package.json has incorrect #platform imports

[jeremymeng]

it should be

  "imports": {
    "#platform/*": {
      "browser": "./src/*-browser.mts",
      "react-native": "./src/*-react-native.mts",
      "default": "./src/*.ts"
    }
  }

The code has

autorest.typescript/packages/rlc-common/src/metadata/packageJson/packageCommon.ts

Lines 120 to 125 in d62d25b

	imports: {
	"#platform/*.js": {
	browser: "./src/*-browser.mjs",
	default: "./src/*.js"
	} as Record<string, string>
	},
