[action] [PR:19118] Increase PTF Container Memory Limits (sonic-net#489)

### Description of PR
Increase the memory and swap limits of the PTF container to 64 GB.

This is necessary for handling the increased memory consumption from the additional `exabgp` processes as a result of the additional number of VM peers of the larger topologies.

To prevent the PTF container from running out of memory when setting up a tesbed for a topology with a large number of VMs.

Increased the memory/swap limits of the PTF docker container in the ansible playbook.

#### How did you verify/test it?
Ran the setup with the new memory limits and confirmed that the setup now succeeds.
