fix: don't quote CloudWatch filter pattern (#702)

BREAKING CHANGE: The filter pattern to match CloudWatch Logs is now passed without modifications to the AWS API. If you're using the Jest `toHaveLog` or Chai `to.have.log` matchers you might need to quote your pattern, e.g. `toHaveLog(pattern) -> toHaveLog("${pattern}")` or `to.have.log(pattern) -> to.have.log("${pattern}")` to support special characters
