Describe the bug

I'm not seeing git-based writing date or last modified dates in my website. They do show up when running a development server with --debug, but not in production.

I added fetch-depth: 0 to my CI build, and I also tried building locally.

Additional context

This bug doesn't appear in v2.0.0-rc.56 but does in v2.0.0-rc.58, which means it was quite recently introduced.

This is fixable by adding plugins.git: { createdTime: true, updatedTime: true } (or simply plugins.git: true) to the theme config, at the cost of also getting git information during development.

The docs mention this approach only in the context of the dev server. I still think there's a regression in how this is handled.

  plugins: {
    git: process.env.NODE_ENV === "production",
  }
}

This is weird because I did not change any related code at all.
