Can't deploy with Kamal after install esbuild

[sbleon]

After installing this gem and using it to install esbuild, the build stage of the Dockerfile doesn't have the tools needed to precompile assets. Here's the error I got:

 [build 6/6] RUN SECRET_KEY_BASE_DUMMY=1 ./bin/rails assets:precompile
 1.342 bin/rails aborted!
 1.342 jsbundling-rails: Command install failed, ensure yarn is installed
 1.370 
 1.370 Tasks: TOP => assets:precompile => javascript:build => javascript:install
 1.370 (See full trace by running task with --trace)
 ERROR: process "/bin/sh -c SECRET_KEY_BASE_DUMMY=1 ./bin/rails assets:precompile" did not complete successfully: exit code: 1

I was able to resolve this issue by adding the following to the build stage of the Kamal-generated Dockerfile after the apt-get install build-essential step.

RUN curl -fsSL https://deb.nodesource.com/setup_20.x -o nodesource_setup.sh && \
    bash nodesource_setup.sh
RUN apt-get install -y nodejs
RUN npm install --global yarn

I don't know if this is something that is generalizable, or if it is needed for all of the various bundlers. But, I suspect that other folks will run into this error and might not have the Docker knowledge needed to fix it.
