Subject: [PATCH] Fix CRLF line endings...

Before:
```
bash: ./update_pwnagotchi.sh: /bin/bash^M: bad interpreter: No such file or directory
```

Thus:
```
scripts/update_pwnagotchi.sh: Bourne-Again shell script text executable, ASCII text, with CRLF line terminators

dos2unix: converting file scripts/update_pwnagotchi.sh to Unix format...

scripts/update_pwnagotchi.sh: Bourne-Again shell script text executable, ASCII text
```

Now it works :)
