secretsmanager_secret - Support adding JSON

SUMMARY
fixes: ansible-collections#656
Amazon supports passing JSON in as the secret as a mechanism for storing and retreiving more complex structures.
While in theory it's possible to pass JSON in as a string to secretsmanager_secret.  However, because Ansible often does funky things with when templated strings are passed to a parameter (ansible-collections#656) it's non-trivial to pass JSON into secretsmanager_secret.
ISSUE TYPE

Feature Pull Request

COMPONENT NAME
secretsmanager_secret
ADDITIONAL INFORMATION
Backstory:
If Ansible sees {{ }} within a string it'll trigger the safe_eval handlers, automatically converting the JSON into a complex structure of lists/dicts, which is then converted to the python string representation of the complex structures - the python string representation is not valid JSON and breaks the AWS integration.
