Describe the bug

Release 1.23.0 introduced #1715. Fix #1717 resolved the issue when API names are provided as arguments but did not correct the problem when no API names are provided.

To Reproduce

We have the following make command to bundle some spec files:

npx @redocly/cli bundle -o ./generated/

As of 1.23.0, it outputs a single file named generated.yaml in the ./ folder:

.
└── generated.yaml

Expected behavior

Before, it would output one file per spec file to the ./generated/ folder.

.
├── generated
    ├── some_spec_file.yaml
    ├── another_spec_file.yaml
    └── ...

OpenAPI description

OAS 3.0.0
