Subject: [PATCH] fix(readme): suppress direnv loading output in cron

By default direnv outputs this while executing:
```
direnv: loading ~/python-itho-wpu/.envrc
```

In a cronjob this results in emails, or when no MTA is configured:
```
CRON[1095]: (CRON) info (No MTA installed, discarding output)
```
