esbuild plugin has undeclared dependency on babel-plugin-syntax-hermes-parser

[welkup]

Describe the issue

The esbuild plugin's index.js file imports from 'babel-plugin-syntax-hermes-parser', but the esbuild plugin does not declare this dependency in its package.json. This results in the following error:

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'babel-plugin-syntax-hermes-parser' imported from //node_modules/@stylexjs/esbuild-plugin/lib/index.js
at new NodeError (node:internal/errors:405:5)
at packageResolve (node:internal/modules/esm/resolve:782:9)
at moduleResolve (node:internal/modules/esm/resolve:831:20)

code: 'ERR_MODULE_NOT_FOUND'
}

Expected behavior

The esbuild plugin should run without the need to install the babel-plugin-syntax-hermes-parser as a direct dependency of the application.

Steps to reproduce

1. git clone https://github.com/facebook/stylex.git
2. mv stylex/apps/esbuild-example/ .
3. cd esbuild-example
4. npm i
5. npm run build

Test case

No response

Additional comments

Can work around by installing the hermes parser as a dependency of your main app.
