Move dotenv from devDependencies to dependencies in package.json

[derektiffany]

Description

Moves dotenv from dependencies to devDepencies in package.json. dotenv is a runtime dependency, and this change will fix issues if NODE_ENV=production or other causes under which dependencies are installed but not devDependencies.

Prior behavior

• export NODE_ENV=production
• npm install
• ISSUER={validOktaDomain}/oauth2/default CLIENT_ID={validClientId} CLIENT_SECRET={validClientSecret} npm run okta-hosted-login-server

Resulted in:

> @okta/samples-nodejs-express-4@3.1.0 okta-hosted-login-server
> node okta-hosted-login/server.js

internal/modules/cjs/loader.js:883
  throw err;
  ^

  requireStack: [
    '/(...)/samples-nodejs-express-4/config.js',
    '/(...)/samples-nodejs-express-4/okta-hosted-login/server.js'
  ]
}

New behavior

The above now results in:

> @okta/samples-nodejs-express-4@3.1.0 okta-hosted-login-server
> node okta-hosted-login/server.js

(...)
App started on port 8080
