add --config (path) flag to CLI to support monorepos

[NiklasBuchfink]

Problem

Monorepos sometimes want to avoid introducing new dependencies inside of the root directory.

Would it be possible to avoid having the new package.json, package-lock.json, inlang.config.js in the root directory of the repository? It would be much better to have these in a subdirectory (ideally inside website/ if possible, or in a new subdirectory) for cleanliness and ease of code owner allocation.

See: LAION-AI/Open-Assistant#3393 (comment)

Proposal

To solve this problem relatively quickly, we can support only one inlang.config.js, find the subdirectory where it is located, and keep the required co-location of inlang.config.js and CLI. The challenge here is that this should work for all inlang apps.

Further information

At some point, monorepos will also request support for multiple applications.

@inlang/team Let's discuss this

Duplicate of #258.

IMO not important because @NiklasBuchfink PR contains a mistake, see LAION-AI/Open-Assistant#3393 (comment). Should we close this for #258?

Counter Proposal - Adding a --config flag to the CLI

The issue stems from the fact that the CLI might be installed in a path.

🎉 The CLI now has a --config option where you can provide your path/to/inlang.config.js.
This makes working with the CLI in monorepos possible and easy!!

Usage

npx inlang lint --config path/to/inlang.config.js
