Fix env templateto ensure compatibility with systemd's EnvironmentFile parsing

[seiuneko]

This commit addresses an issue in the Vaultwarden project's .env.template file where comments explaining environment variable options were incorrectly placed on the same line as the variable definitions. Systemd's EnvironmentFile directive only recognizes comment symbols (#) at the beginning of a line. Therefore, explanatory comments placed on the same line as environment variable definitions can lead to misinterpretations or errors when the file is used in a systemd service file.

I'm not happy with just moving the comments on their own line. Can you improve the wording of the smtp security settings? Since the SMTP_PORT default depends on the SMTP_SECURITY setting this could probably be put more succinctly.

vaultwarden/src/config.rs

Lines 656 to 657 in 897bdf8

	/// Port
	smtp_port: u16, true, auto, |c| if c.smtp_security == *"force_tls" {465} else if c.smtp_security == *"starttls" {587} else {25};

And regarding the ROCKET_PORT I'd say that we should change the default to 8000 and explain that we use port 80 in the container image instead of vice versa.
