[docs] improve and fix entry for analyze.include-dependencies (#15197)

## Summary

Changes two things about the entry:
* make the example valid TOML - inline tables must be a single line, at
least till v1.1.0 is released,
but also while in the future the toml version used by ruff might handle
it, it would probably be
good to stick to a spec that's readable by the vast majority of other
tools and versions as well,
especially if people are using `pyproject.toml`. The current example
leads to `ruff` failure.
See https://github.com/toml-lang/toml/pull/904
* adds a line about the ability to add non-Python files to the map,
which I think is a specific and
important feature people should know about (in fact, I would assume this
could potentially
become the single biggest use-case for this).

## Test Plan

Ran doc creation as described in the
[contribution](https://docs.astral.sh/ruff/contributing/#mkdocs) guide.
