Remove libcurl dependency

[epikur-io]

Summary

When building the Kong docker image for Ubuntu, some cURL/libcurl related CVE findings occur in the image when perfoming a container security scan.

cURL is purged after usage inside the Dockerfile, but the libcurl dependency is left. Container security scanners find CVEs related to cURL (like CVE-2023-38545). By adding --autoremove option to the purge command, the libcurl dependency will also get purged.
