templates: add filter to reverse list The filter supports only lists because for lists, it’s straightforward to implement. Reversing text doesn’t seem very useful and is hard to implement. Reversing the bytes would break multi-bytes encodings. Reversing the code points would break characters consisting of multiple code points. Reversing graphemes is non-trivial without using a library not included in the standard library.

Check if Cargo.lock is up-to-date. Will fail with a 101 error code if not.

However most CIs will run `cargo build` or similar before running the tests, so we need to check if it was modified
