fix: scripts.*.exec.failFast option in melos.yaml

[alex-sandri]

Description

--fail-fast is a flag and not an option and as such does not accept any value.

Example

This config is currently broken as in the generated command --fail-fast true is not valid syntax.

scripts:
  lint:
    run: flutter analyze
    exec:
      failFast: true
      concurrency: 1
