Users may need to ignore 127.0.0.1 in SSH config to use Podman 5.3

[calebevans]

Issue Description

After updating to 5.3, I started receiving the following error:

caevans@caevans-mac reportportal-connector % podman --log-level=debug ps

Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM
Error: unable to connect to Podman socket: failed to read identity "~/.ssh/id_ed25519": open ~/.ssh/id_ed25519: no such file or directory
DEBU[0000] Shutting down engines

I found that adding !127.0.0.1 and !localhost to the wildcard rule resolved my issue:

Host * !127.0.0.1 !localhost
  UseKeychain yes
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_ed25519

Steps to reproduce the issue

Steps to reproduce the issue

1. Install Podman 5.3
2. Don't exclude 127.0.0.1 or localhost in your SSH config rules
3. Execute a Podman command

Describe the results you received
