ec2_asg: Change purge_tags default value to False

SUMMARY

Changed default value of purge_tags to False.

With the addition of purge_tags to ec2_asg module ansible-collections#960, the default value was kept to True similar to many other modules in this collection and also as specified in ansible dev guide.
With this addition, the issue was discovered that there is a possibility of this change breaking existing playbooks for users if they don't update their playbooks and specify purge_tags: false where required.
This PR's change will prevent accidental breakage.
