[Bug(CLI)]: query block can no longer be used to get the most recent block

[SpicyLemon]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

$ simd query block
Error: accepts 1 arg(s), received 0
...

This command used to allow zero args as a way to get the most recent block.

It also used to default to taking in the height, but now defaults to hash, which was a breaking change.

Cosmos SDK Version

v0.50.7

How to reproduce?

Hi! The breaking change was mentioned in the changelog: https://github.com/cosmos/cosmos-sdk/pull/14659/files#diff-06572a96a58dc510037d5efa622f9bec8519bc1beab13c9f251e97e657a9d4edR263.

However we can bring back the no argument behavior!

The breaking entry isn't really helpful. It both says that the command was removed, but that it still exists. And it doesn't mention that the height/hash is now required and that in order to provide a height, you now have to include --type height.

The --type flag should also default to height. That, combined with making the arg optional would make the command behave exactly like it did before, but with the added ability to get a block by its hash.

Also, I just noticed that the hash fields from that command are now base64 encoded rather than hex. Hex is better for those because that's how those hashes are always referred to.

The addresses in the results are also base64 encoded which isn't how addresses are ever used.

We can't do that. That would be breaking in a patch version.
