[Bug]: rules_esbuild does not properly pass `deps` to js_binary

What happened?

I have an esbuild rule that I would assume is bundling a small config and it should have dependencies built into the output. However, on CI we found that the bundled config was missing the node_modules that were passed into the deps array for the esbuild rule call. See example code below

esbuild(
    name = "_syncpack.config.min",
    entry_point = "syncpack.config.js",
    # This file must always be CJS for syncpack to not ignore it
    # If it is not CJS, syncpack will silently fail and default
    # to it's own config, which will cascade into a failure on
    # our end since it will fail to exit 1 on CI
    format = "cjs",
    minify = True,
    # setting node as the platform will default us to CJS
    platform = "node",
    target = "esnext",
    deps = [
        "//arcanist/linters/linters/syncpack:node_modules",
    ],
)

bin.syncpack_lint_semver_ranges_binary(
    name = "lint-semver-ranges",
    args = [
        "--config",
        "$(execpath :_syncpack.config.min.js)",
    ],
    # this sets the tool to run from the root of the monorepo source tree
    chdir = "$$BUILD_WORKSPACE_DIRECTORY",
    data = [
        ":_syncpack.config.min.js",
    ],
)

This manifested in the config silently failing due to missing dependencies which I fixed by passing node_modules to the data array in the js_binary.

Note, the js_binary target is executed via bazel run

How to reproduce

Bazel run a target that takes a config built with esbuild as input and pass it to the runner. In this case, it's syncpack. Feel free to also reach out to me for more info.

Any other information?
