Corepack packageManager set to pnpm triggers warning with assets:precompile

[jprosevear]

• [x] I have tried upgrading by running bundle update vite_ruby.
• [x] I have read the troubleshooting section before opening an issue.

Description 📖

With corepack enabled and packageManager set (to pnpm in my case), running rake assets:precompile will throw a warning (but continue):

/Users/jpr/.asdf/installs/nodejs/20.14.0/lib/node_modules/corepack/dist/lib/corepack.cjs:22373
              throw new UsageError(`This project is configured to use ${result.spec.name} because ${result.target} has a "packageManager" field`);
                    ^

UsageError: This project is configured to use pnpm because /Users/jpr/src/Rhino/mono-test/rhino-project-template_rails_mono/package.json has a "packageManager" field
    at Engine.findProjectSpec (/Users/jpr/.asdf/installs/nodejs/20.14.0/lib/node_modules/corepack/dist/lib/corepack.cjs:22373:21)
    at async Engine.executePackageManagerRequest (/Users/jpr/.asdf/installs/nodejs/20.14.0/lib/node_modules/corepack/dist/lib/corepack.cjs:22404:24)
    at async Object.runMain (/Users/jpr/.asdf/installs/nodejs/20.14.0/lib/node_modules/corepack/dist/lib/corepack.cjs:23096:5) {
  clipanion: { type: 'usage' }
}

I have traced this to: https://github.com/ElMassimo/vite_ruby/blob/a3182a9b8abc058004e47b81b214ea6e578e7e6f/vite_ruby/lib/tasks/vite.rake#L92

Because it runs the yarn command (when it is not installed), triggering the warning. I suspect that yarn call should either:

• Check for the 'yarn' binary before running the command OR
• Only run this if yarn is the package manager

This doesn't seem to be a problem since everything still gets installed, but it would be nice to remove the warning.
