Admin password improperly substituted during installation

[grahamalama]

Describe the bug

It appears that the password that I set during the app installation through the web interface was improperly substituted.

Context

• Hardware: Raspberry Pi v4 at home
• YunoHost version: 11.2.12
• I have access to my server: Through SSH
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: 2022.09.01~ynh4

Steps to reproduce

• initiate install process through web interface
• enter an admin password
  • For obvious reasons I don't want to paste the exact password I used, but for the sake of this bug report, I'll stay it started with <special character><alpha character><...rest of password>
• app installation is successful
• try to use password on login screen. Login fails
• SSH into server
• cat /var/www/photoprism/.env | grep "ADMIN"
• output is <special character><alpha character>__PASSWORD__<..rest of password>

Expected behavior

• password is exactly the one that was set in the app installation form
