Make build -with-deps a default behaviour

[DZakh]

Here's the discussion from the forum about the change https://forum.rescript-lang.org/t/proposal-make-build-with-deps-a-default-behaviour/3832

Implementation

1. I've kept the -with-deps parsing even though it doesn't do anything anymore, so there's no `unknown option: '-with-deps' error. Removing it completely in the next major version might be a good idea.
2. It's my first contribution to the compiler, and I'm excited to do more stuff in the future. I had to overcome a little barrier that it's something scary to do.
3. I couldn't make the ocamlformat work, so if it should work for the project, please let me know how.

Fixing tests 🧑‍💻

@cknitt @christian-schulze It's ready for review 😁

[cknitt]

LGTM! @cristianoc What do you think?

[cknitt]

(I fear you'll need to rebase again now that I have merged #6352.)

[cristianoc]

Looks good.
The only thing the description is not explicit about is whether this is a breaking change in some cases.

[cknitt]

Hmm, there is an error running the tests now that I don't quite understand.

[DZakh]

There's an extra line break in the error, I'll fix

Highlighting that I've changed the text a little bit.

Then we should not forget to change it again when we change the names of the fields for rescript.json. Since we probably will ditch the bs- prefix here as well.

Or you phrase it more generally, like:
Did you add it to the dependencies in the compiler configuration file?
(which is arguably a bit more confusing)

[DZakh]

Did you add it to the dependencies in the compiler configuration file?

This one is good if we are going to keep both bsconfig.json and rescript.json for a while. Otherwise, it should be changed together with replacing bsconfig.json with rescript.json in all places where it mentioned.

[fhammerschmidt]

I am indifferent. What do you think @cknitt @cristianoc @zth ?

[zth]

I think it's fine to leave it like it is. We'll do a search replace for bsconfig -> rescript anyway when it's time.
