Revert master to v0.18.4 (current GA release)

[Nuru]

what

• Revert main to v0.18.4

why

• PR feat: use security-group module instead of resource #73 converted this module to use an experimental and since abandoned version of the security group module. This was published as version 0.19.0. 0.18.4 was the last version published before that modification, and the last supported version. This PR reverts the master branch to version 0.18.4 in preparation for providing a compatible version 1.0 of this module using security group module v2.0.
