[FR] - Make `json` formatted output explicit

[nielstron]

Internal/External External otherwise.

Area Other Any other topic (Delegation, Ranking, ...).

Describe the feature you'd like The json-formatted query utxo output should be obtainable by providing an optional --json flag or sth similar. Currently the output is automatically json-formatted when using --out-file. This is terrible for many reasons, some of them

• It is completely undocumented
• There is a semantic difference between cardano-cli query utxo ... > file and cardano-cli query utxo ... --out-file file which is... unintuitive to say the least
• The current canonical way to get json formatted output from the node is cardano-cli query utxo ... --out-file /dev/stdout... no more comments.

Describe alternatives you've considered None

Additional context / screenshots None
