This finishes the work started in
https://github.com/emscripten-core/emsdk/pull/1388 by fixing CI. It
avoids a breaking change by:
* Using the latest rules_js 1.x.x version, instead of updating to
rules_js 2 (which removes support for bazel 5).
* Copying the contents of
[rules_js_dependencies](https://github.com/aspect-build/rules_js/blob/main/js/repositories.bzl)
instead of calling it, as the call would need to be added by users in
their `WORKSPACE` files
Context from the previous PR:
> Bazel's Node.js dependency comes from
[rules_nodejs](https://github.com/bazelbuild/rules_nodejs/). Previously,
bazel/deps.bzl was using rules_nodejs 5.8.0, released in 2022 and only
supported Node.js toolchains up to 18.12.1.
> This PR bumps rules_nodejs to latest 6.1.1. It also replaces
build_bazel_rules_nodejs with
[rules_js](https://github.com/aspect-build/rules_js), since npm_install
that bazel/emscripten_deps.bzl used was deprecated. The README of
rules_nodejs now recommends migrating to rules_js for everything other
than the Node.js toolchain:
(371e8cab15)
> Impetus
Our repo builds with Bazel and uses Emscripten and Node.js. Tried to
upgrade Node.js 18 to Node.js 20 and saw that emsdk didn't support
rules_nodejs 6+ in the same workspace.
Similarly, it's not possible to update to rules_js v2 in a workspace
that also references `emsdk`.
