[BUG] fvm flutter run behavior change in 2.x

[ened]

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.
• If you are on Windows. Make sure you are running the terminal as administrator or with developer permissions.

Describe the bug

We used to successfully run fvm flutter pub global run melos run test:unit:flutter to run some unit tests via a melos pipeline, however the same invocation now fails with the flutter command not being available anymore. Instead things now fail like this:

fvm: running version "1.22.6"

melos run test:unit:flutter
   └> melos exec -c 5 --fail-fast --dir-exists=test --ignore="*example*" --ignore="*web*" -- \  "mkdir -p test-results && flutter test --machine > test-results/flutter-test.json && exit 0"
       └> RUNNING

$ melos exec
   └> mkdir -p test-results && flutter test --machine > test-results/flutter-test.json && exit 0
       └> RUNNING (in 6 packages)

--------------------------------------------------------------------------------
[connect]: /bin/sh: line 1: flutter: command not found
[mnc_support]: /bin/sh: line 1: flutter: command not found
--------------------------------------------------------------------------------

The relevant bit in melos.yaml is:

  test:unit:flutter: >
    melos exec -c 5 --fail-fast --dir-exists=test --ignore="*example*" --ignore="*web*" -- \
      "mkdir -p test-results && flutter test --machine > test-results/flutter-test.json && exit 0"

• OS: mac
• FVM Version 2.0.2
