ssh-2.0.9 breaks backwards compatibility with older Azure CLI versions < 2.71.0

### Describe the bug

The recent upgrade of the extension `ssh` to version `2.0.9` #9778 has introduced a dependency on a later version of Azure CLI without updating `azext_metadata.json`. Users with pinned versions of `azure-cli` < `2.71`, installing a non-pinned version of `ssh` will install the incompatible version `2.0.9`.

### Reproduction steps
```pwsh
# Install a pinned version of Azure CLI
choco install azure-cli --version=2.56.0 -y
# Install the latest compatible version of the ssh extension
az extension add --name ssh --system
# Run az ssh vm
az ssh vm --ip xx.xx.xx.xx
```

### Related command

`az extension add --name ssh`
`az ssh vm --ip xx.xx.xx.xx`

### Errors

```pwsh
The command failed with an unexpected error. Here is the traceback:
No module named 'azure.cli.command_modules.vm.operations'

### Issue script & Debug output

```pwsh
az --version
azure-cli 2.56.0
az extension list-versions --name ssh
# truncated for clarity
{
"compatible": true,
"experimental": false,
"installed": true,
"name": "ssh",
"preview": false,
"version": "2.0.9 (max compatible version)"
}

### Expected behavior

`ssh` version `2.0.9` should have compatibility restricted to `azure-cli` version >= `2.71.0`

Executing `az extension add --name ssh` with `azure-cli` < `2.71.0` should install version `2.0.8`, which is the last compatible version.

### Environment Summary

### Additional context

`azure.cli.command_modules.vm.operations.vm import VMShow` appears to have been introduced in `azure-cli` version `2.71.0`

Start with the ssh extension's azext_metadata.json and inspect how Azure CLI compatibility is declared for versions 2.0.9 and 2.0.8. Reproduce with Azure CLI 2.56.0 using the listed extension commands; done means 2.0.9 requires Azure CLI >=2.71.0 and older CLI versions select 2.0.8.
