We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
False positive detecting OctalPermissionsRule
When trying to setgid permissions

```
[ANSIBLE0008] Octal file permissions must contain leading zero
mode: 02775
```

Looks like the regex requires exactly 3 digits, which is not always correct.

```
# At least an indent, "mode:", optional whitespace, any digits, EOL
mode_regex = re.compile(r'^\s+mode:\s*[0-9]+\s*$')
# Same as above, but with a leading zero before three digits
valid_mode_regex = re.compile(r'^\s+mode:\s*0[0-7]{3}\s*$')
```
