Consider enabling dependabot

[thomaseizinger]

Several dependencies across the repository are outdated.

Outdated dependencies often lead to a wasting time on bugs that have already been fixed upstream. For example, I keep running into a bug during development where wasm-pack is not found which leads to me having to nuke node_modules to re-install it again.

The latest version of https://github.com/wasm-tool/wasm-pack-plugin no longer automatically installs wasm-pack but instead always expects it to be in $PATH which is much more robust.
