fix: hostname and proxy command generation (#95)
- latest Coder versions won't accept the SSH connections if proxy command does not include the workspace owner name - for wildcard configuration the ssh config stays the same but the actual hostname provided to the Toolbox will include the workspace owner name For wildcard config: - the ssh config hostname follows the `coder-jetbrains-toolbox-dev.coder.com--*` pattern - the proxy command will have a similar host prefix - the hostname provided to Toolbox follows the `coder-jetbrains-toolbox-dev.coder.com--${ws.ownerName}--${ws.name}.${agent.name}` pattern For non wildcard config: - the ssh config hostname follows the `coder-jetbrains-toolbox--${ws.ownerName}--${ws.name}.${agent.name}--dev.coder.com` pattern - the proxy command will have the username and hostname in the ${ws.ownerName}/${ws.name}.${agent.name} format - the hostname provided to Toolbox follows the `coder-jetbrains-toolbox-dev.coder.com--${ws.ownerName}--${ws.name}.${agent.name}` pattern - resolves #94
