Version task fails if .lando.yml contains invalid config

[AaronFeledy]

Since updated packages can be defined in .lando.yml, it makes sense that lando loads it to get versions. However, in situations such as those created by setup-lando in GHA, where a slim version of Lando is installed but service plugins are not yet downloaded, Lando throws errors on lando version about invalid service types in .lando.yml. This is causing most of the official Lando plugin's tests to fail because setup-lando validates the version before running lando setup.

Lando should probably have special error handling around tasks like version so that it will always succeed if obtaining the version is at all possible, even if other error states are present.
