Current Behavior

I deployed an instance of lowcoder using both of these instructions:

• https://docs.lowcoder.cloud/lowcoder-documentation/setup-and-run/self-hosting
• https://github.com/lowcoder-org/lowcoder/blob/main/deploy/docker/README.md

Even if I set ENABLE_USER_SIGN_UP environment variable as false, the "Sign Up" link is visible and functional. Anyone can just access my instance and create an account.

Expected Behavior

When ENABLE_USER_SIGN_UP is set to false, there should be no "Sign Up" link in the login page.

Steps to reproduce

1. Create an instance of the all-in-one docker version of lowcoder, making sure that ENABLE_USER_SIGN_UP is set to "false".
2. The "Sign Up" link is visible in the login page.

Environment

• Docker version 20.10.14, build a224086
