[Bug] A small problem in commonds for Synology

[bootcamp6]

Describe the bug
In the commond of download cloudflareddns.sh
wget https://raw.githubusercontent.com/joshuaavalon/SynologyCloudflareDDNS/master/cloudflareddns.sh -O /sbin/cloudflaredns.sh

The file has been renamed as cloudflaredns.sh (not cloudflareddns.sh)

Then if the user just copy the code in step 3:
cat >> /etc.defaults/ddns_provider.conf << 'EOF'
[Cloudflare]
modulepath=/sbin/cloudflareddns.sh

In this case, the Synology DDNS setting cannot find correct file to run the commonds.
