guide: split DVC Files/Internals (prep for dvc.yaml 2.0 updates)

[jorgeorpinel]

Also includes

• Separate Outputs and Dependencies sections in DVC Files guide

Next up:

• Review "metafile" terminology.
• Introduce basics from https://github.com/iterative/dvc/wiki/Parametrization to the DVC Files guide
• Further split DVC Files into separate pages?

@ivan most files just have link updates, please focus on sidebar.json, user-guide/dvc-files.md, and user-guide/dvc-internals.md. The changes can be checked more easily in https://dvc-landing-dvc-yaml-pa-e4wbve.herokuapp.com/doc/user-guide

This link is meant to preserve/transfer the SEO ranking for the now separate guide on internals.

there are failing links on CI^?

[jorgeorpinel]

p.s. I almost forgot to update content/linked-terms.js and to add a redirects-list.json!

CI checks are passing now BTW 🙂

[jorgeorpinel]

OK I see the failed links now. These are fine, as they don't exist on prod yet. But they will soon, merging!

I did a sanity check of the redirect and .dvc, dvc.yaml auto-links in https://dvc-landing-dvc-yaml-pa-e4wbve.herokuapp.com/doc/user-guide/dvc-files-and-directories

This also "applies" to v1 but no need to backport.

I guess we will need good reasons to backport things to v1 e.g. existing PRs (pre-2.0) and bug fixes.

⚠️ Hmmmm... https://dvc.org/doc/user-guide/dvc-files-and-directories is giving me a 404 but the redirect is there:

dvc.org/redirects-list.json

Line 32 in ecc0708

"^/doc/user-guide/dvc-files-and-directories$ /doc/user-guide/dvc-files",

I tested in the review app before merging.
