Same symptom as #68992. Fixed on 3006.x by #69339 (#69339), on master/3008.x by #68871 (#68871). Opened #69463 (#69463) to backport the removal to 3007.x.

Root cause: vendored linode-python 1.1.1 targets the retired Linode API v3 and uses is/is not with integer literals. Python 3.12+ raises SyntaxWarning on import. salt.cloud.clouds.linode already uses Linode APIv4 over HTTP/JSON and never imported linode-python, so the package is vestigial and safe to drop.
