Rollup merge of #139919 - GuillaumeGomez:rustdoc-json-1-indexed, r=aDotInTheVoid
Make rustdoc JSON Span column 1-based, just like line numbers

Fixes https://github.com/rust-lang/rust/issues/139906.

This PR does two things:
 1. It makes column 1-indexed as well, just like lines.
 2. It updates documentation about them to mention that they are 1-indexed.

I think it's better for coherency to have them both 1-indexed instead of the weird mix we used to have. Docs for `line` and `col` fields can be found [here](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_span/struct.Loc.html#structfield.line).

And finally: it adds a regression test to ensure they are indeed 1-indexed.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
