I had this set to off because it was interfering with checking if the
line goes beyond 100 columns. But `cargo fmt` mostly takes care of that
anyway. Leave it up to the user/workspace settings rather than the
project one.
Currently the workspace's version is older than VS Code's default.
VS Code complains about things that aren't errors according to the
workspace. (In particular, typing of catched exceptions has become
stricter.) With this setting, you can select the workspace's Typescript
version in the VS Code UI so the two are consistent.
