Merge #2991

2991: vscode: updated rollup typescript so it typechecks the bundle r=Veetaha a=Veetaha

See [this happy update](https://github.com/rollup/plugins/blob/master/packages/typescript/CHANGELOG.md#v300) from `@rollup/typescript-plugin` changelog)

I also added a utility script to view the latest dependencies versions (`dry-run` variant) and update them in batch. Beware, that it bumps versions even if the major version of them has changed (for updating only within one major version there is a cli option, but I didn't want add a whole bunch of scripts)
Some of the dependencies major versions are out of date:
```
~/my/projects/rust-analyzer/editors/code (feature/refactoring-vscode-ext) $ npm run bump-deps:dry-run
