[BUG] fvm use stable --pin gets interactive in CI environment

[twogood]

Before creating a bug report please make check the following

• You have read our FAQ
• If you have used flutter. Please install correctly, run pub cache repair. Close the terminal and try again.
• Run fvm doctor if possible and add the output to the issue.

Describe the bug
I'm trying to create a GitHub action that tries to upgrade to the latest Flutter stable (fvm use stable --pin) and create a PR if there is a new version.

To Reproduce

name: Update Flutter Version in FVM

on:
  workflow_dispatch:
  schedule:
    - cron: '0 0 * * 0' # Weekly

env:
  CI: true

jobs:
  update-flutter-version:
    runs-on: ubuntu-latest
    steps:
      - name: Check out repository
        uses: actions/checkout@v4

      - name: Set up Dart
        uses: dart-lang/setup-dart@v1

      - name: Install FVM
        run: dart pub global activate fvm

      - name: Run FVM use stable --pin
        run: fvm use stable --pin

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v3
        with:
          commit-message: "Update Flutter version to latest stable"
          title: "Update Flutter version to latest stable"
          body: "This PR updates the Flutter version to the latest stable release. Tip: close and reopen this PR to trigger the GitHub Action for PRs!"
          branch: "update-flutter-stable-${{ github.run_number }}"
          delete-branch: true

What happens though is that fvm asks "Would you like to install it now? (y/n)" even in the CI environment.

Expected behavior
I would like fvm to not require interaction when running in a CI environment and the "CI" environment variable is included in kCiEnvironmentVariables. If it installs or not installs Flutter by default is not important.

@twogood I believe this has been addressed in the latest version, as FVM detects if it is CI in order to use interactivity. I will close this issue, but please reopen it if that is not your experience.

Works with fvm 3.2.1, thanks a bunch!
