Reintroduce documentation comparing Inko to other languages
We used to have a page in the manual that compared Inko to a few other languages, but it was a bit of a drag/too verbose to read. We should reintroduce a similar page, but perhaps just using an HTML table that compares a few different facts (e.g. the memory management style, license, etc).
Some languages/runtimes to compare to:
- Go
- Lunatic (https://lunatic.solutions/)
- Erlang
- Exlir
- Gleam
- Pony
- Ruby
- Python
- Rust
