[BUG] configuration documentation: MONGO_USER and MONGO_PASS must be urlencoded when special characters are present

Is there an existing issue for this?

[X] I have searched the existing issues

Current Behavior

If a password (or username) contains special characters the container does not run properly, the error is not available on stdout but only in server.log To fix this it is required to clear the unifi config dir, as the username and password are persisted after first boot.

Expected Behavior

The documentation should include a note to use urlencoding on password and username if they contain special characters.

Steps To Reproduce

set up a mongodb user with a password containing special characters. Use unencoded password in MONGO_PASS. Service was not started, server.log contains error message.

Environment

- OS: armbian
- How docker service was installed: using docker apt repository

CPU architecture
