Support setting bunfig.toml programatically

[tommyboylab]

What is the problem this feature would solve?

I am trying to migrate my CI/CD pipelines to use Bun but have an issue setting the configration for private repositories as I cannot programatically set them in the GH action like I can with npm ex: npm config set.

I believe there is an open issue for reading from .npmrc which would resolve this issue here, but I would also like the ability to set this directly in the bunfig.toml in a similar way (maybe bun config set install-scope '...'?)

What is the feature you are proposing to solve the problem?

Let users add configuration to bunfig.toml programatically -- bun config set [configOption] '...'

What alternatives have you considered?

I've tried to create a file by using cat, but with the specific structure of [option] ... [option2] ... it's not really possible lint the file. Having a way that does this automatically would be extremely helpful.
