dockerd container is missing ssh

[Nugs]

• I have tried with the latest version of Docker Desktop
• I have tried disabling enabled experimental features
• I have uploaded Diagnostics
• Diagnostics ID: 517C6036-A85F-4F84-8011-18C16E3BED7C/20210811184549

Expected behavior

Using docker buildx build with git URL specified requiring SSH should successfully source the build context from the remote repository.

Actual behavior

➜ docker buildx build git@github.com:***/***.git
[+] Building 0.3s (1/1) FINISHED

SSH does not appear to be contained within the container running the build.

Information

• macOS Version: Mojave (10.14.6)
• Intel chip or Apple chip: Intel
• Docker Desktop Version: 3.5.2 (66501)

Steps to reproduce the behavior

1. Attempt to source a docker build from an SSH git URL e.g. docker buildx build git@github.com:docker/buildx.git
2. Note the error ssh -F /dev/null -o UserKnownHostsFile=/var/lib/docker/tmp/544077690: ssh: command not found
