Fix missing requires for tap-info command

[kmontag]

Previously, running brew tap-info --installed --json in a github actions linux runner would throw:

Error: uninitialized constant Homebrew::API
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/tap.rb:1359:in `formula_names'
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/tap.rb:868:in `to_hash'
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/cmd/tap-info.rb:87:in `map'
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/cmd/tap-info.rb:87:in `print_tap_json'
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/cmd/tap-info.rb:37:in `run'
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/brew.rb:95:in `<main>'

After the setup steps:

    steps:
      - name: Set up Homebrew
        id: set-up-homebrew
        uses: Homebrew/actions/setup-homebrew@master
        with:
          token: ${{ github.token }}

      - name: Cache Homebrew Bundler RubyGems
        id: cache
        uses: actions/cache@v3
        with:
          path: ${{ steps.set-up-homebrew.outputs.gems-path }}
          key: ${{ runner.os }}-rubygems-${{ steps.set-up-homebrew.outputs.gems-hash }}
          restore-keys: ${{ runner.os }}-rubygems-

      - name: Install Homebrew Bundler RubyGems
        if: steps.cache.outputs.cache-hit != 'true'
        run: brew install-bundler-gems

I wonder if we want to limit the tap-info command to only loading locally installed taps as if it wasn't using the API. It seems like the original intent of the command is to only show info for locally installed taps.

That would remove the need to add require "api" in this case though it might be needed for some other code paths. This bug is most likely related to this recent PR: #17707

I'm not able to reproduce these errors on macOS on this branch either. I wonder why it'd behave differently on Linux here.

[kmontag]

Yeah, I'm also not able to reproduce on macOS, or weirdly even with the brew docker image. I only see the error on linux in the github actions context.

Here's a simple demo of the issue: kmontag/brew-pr-17778-demo#1

And the log from the associated failed run in case it isn't visible:

Thanks for fixing this!
