fix(bindings/cli): Rename --config to --config-json

[titanous]

Description:

@swc/cli uses a different format for --config, so use a different name.

BREAKING CHANGE:

Experimental --config option has been renamed to --config-json.

Related issue (if exists): #4017 (comment)

I wish it would just be --config and match semantics, but I agree this is an improvement over what's on HEAD right now, and you could add --config back to swcx later such that it matches.

[titanous]

Unfortunately for the purposes of rules_swc, the old semantics are unworkable: we need to be able to pass arbitrary plugin configuration, which would require a really annoying flattening routine to spread every part of the config object into separate CLI args and even then it would be lossy without type information.

@titanous can you make this non breaking by leaving --config in and emitting a warning for using it and say it will be breaking in the future? Just makes the adoption right now slightly easier.

Although I guess the other was already experimental. It's really unclear to me if the rust binary is considered stable or not from what I can see publicly on the docsite etc.

[titanous]

I'd prefer to just rename it quickly given that it was already marked as experimental and this release has only been out for a few days. Otherwise the breakage in the future will be bigger, not everyone reads warnings.

[Aghassi]

Sounds good to me thanks!

Thanks!
