Cannot add a module in pnpm root workspaces

[cjpearson]

When the Nuxt application is the root of a pnpm workspace, the module add command fails.

❯ pnpm dlx nuxt module add @nuxtjs/tailwindcss

 ERR_PNPM_ADDING_TO_ROOT  Running this command will add the dependency to the workspace root, which might not be what you want - if you really meant it, make it explicit by running this command again with the -w flag (or --workspace-root). If you don't want to see this warning anymore, you may set the ignore-workspace-root-check setting to true.

 ERROR  corepack pnpm add @nuxtjs/tailwindcss@6.14.0 failed.

The addDependency function from nypm does support a workspace: true option, but in that case it would fail if run outside of a workspace root. I don't know if this is a common case, but maybe it would be possible to detect if it's run in a workspace root and set the option accordingly?
