Handle edge case where it is expected ssh:// urls to have at least one @ symbol

The issue

Fixes Issue #5849

The fix

I think ssh:// urls require at least one @ and so checking for 2 or more in this case should be sufficient.

The checklist

• Associated issue
• A news fragment in the news/ directory to describe this fix with the extension .bugfix.rst, .feature.rst, .behavior.rst, .doc.rst. .vendor.rst. or .trivial.rst (this will appear in the release changelog). Use semantic line breaks and name the file after the issue number or the PR #.
