config: Expand default security.exec.osEnv policy

Browse source 
To better support private Hugo modules and automatically
launching a text editor on content creation, this change
adds the following environment variables to the default
security policy:

- HOME
- XDG_CONFIG_HOME
- USERPROFILE
- SSH_AUTH_SOCK
- DISPLAY
- LANG

Fixes #9333
