Migrate from rules_nodejs to rules_js/rules_ts (take 2) (#7928)
* Migrate from rules_nodejs to rules_js/rules_ts (take 2)

This is the second version of patch #7923. The first version got
reverted because bazel query was failing:

    $ bazel --nosystem_rc --nohome_rc query tests(set('//...')) except tests(attr("tags", "manual", set('//...')))
    ERROR: Traceback (most recent call last):
    	File "/workdir/tests/ts/bazel_repository_test_dir/BUILD", line 6, column 22, in <toplevel>
    		npm_link_all_packages(name = "node_modules")
    	File "/var/lib/buildkite-agent/.cache/bazel/_bazel_buildkite-agent/ec321eb2cc2d0f8f91b676b6d4c66c29/external/npm/defs.bzl", line 188, column 13, in npm_link_all_packages
    		fail(msg)
    Error in fail: The npm_link_all_packages() macro loaded from @npm//:defs.bzl and called in bazel package 'tests/ts/bazel_repository_test_dir' may only be called in bazel packages that correspond to the pnpm root package '' and pnpm workspace projects ''

This was happening because the `.bazelrc` file only added
`--deleted_packages` to the `build` command. We also need it for the
`query` command. This second version of the patch fixes that.

Original commit message:

This patch migrates the current use of rules_nodejs to the new rules_js.
rules_js is the intended replacement of rules_nodejs as per this note:
https://github.com/aspect-build/rules_js#relationship-to-rules_nodejs

> rules_js is an alternative to the build_bazel_rules_nodejs Bazel module
> and accompanying npm packages hosted in
> https://github.com/bazelbuild/rules_nodejs, which is now
> unmaintained. All users are recommended to use rules_js instead.

There are a few notable changes in this patch:
1. The `flatbuffer_ts_library` macro no longer accepts a `package_name`
   attribute. This is because rules_js appears to manage the import
   naming of dependencies via top-level `npm_link_package` targets.
   Users will have to migrate.
2. I added a few more arguments to `flatbuffer_library_public()`. These
   helped with exposing esbuild to `ts/compile_flat_file.sh`.
3. I pinned the version of `typescript` in `package.json` so that
   rules_ts can download the exact same version. rules_ts doesn't know
   what to do if the version isn't exact.
4. Since rules_js uses the pnpm locking mechanism, we now have a
   `pnpm-lock.yaml` file instead of a yarn lock file.
4. I added bazel targets for a few of the existing tests in `tests/ts`.
   They can be run with `bazel test //test/ts:all`. Since there is no
   flexbuffers bazel target, I did not add a bazel target for the
   corresponding test.
5. I added a separate workspace in `tests/ts/bazel_repository_test_dir/`
   to validate that the flatbuffers code can be imported as an external
   repository. You can run the test with
   `bazel test //test/ts:bazel_repository_test`. For this to work, I
   needed to expose a non-trivial chunk of the flatbuffers code to the
   test. I achieved this through some recursive `distribution`
   filegroups. This is inspired by rules_python's workspace tests.

I did not do anything special to validate that the `gen_reflections`
parameter works the same. This patch doesn't change anything about
the TypeScript generation.

As a side note: I am not an expert with rules_js. This patch is my
attempt based on my limited understanding of the rule set.

Fixes #7817

* Fix the query
