Feature request: commenting and deactivation of config options

[StableLlama]

The config.json has many config options but doesn't allow to temporarily disable one or write a comment about why a setting was made.

Feature request:

Be a bit more liberal when parsing the config content and allow entries where the key is starting with a # or // and then ignore that key/value.

So you could easily have a line like

...
    "--train_batch_size": 6,
...

and then quickly disable it by changing it to

...
    "#--train_batch_size": 6,
...

or you could even be more verbose

...
    "# StabeLlama 08.06.25: disable batch training for testing on a small machine": "",
    "#--train_batch_size": 6,
...

ok, don't use json then, use yaml or toml?

How? The documentation is only talking about a JSON, e.g. at https://github.com/bghira/SimpleTuner/blob/main/OPTIONS.md
