The flags to check this are a little bit messed up now.

Currently, we allow both spec-name and version to be relaxed via this misleading flag name:

https://paritytech.github.io/substrate/master/try_runtime_cli/struct.SharedParams.html#structfield.no_spec_name_check

We should rename this flag to no_spec_check.

Possible we should also prevent spec names from EVER not matching, because it is almost certainly a footgun, at least in some commands such as on-runtime-upgrade. But something to be discussed.
