The packageFiles of type plain-text are not parsed and there is fallback to latest repository tags even if it's OK

Describe the bug
Using [email protected] with the following configruration:

{
    "packageFiles": [
        {
            "filename": "VERSION",
            "type": "plain-text"
        }
    ],
    "bumpFiles": [
        {
            "filename": "VERSION",
            "type": "plain-text"
        }
    ],
    "scripts": {
        "prechangelog": "rm CHANGELOG.md"
    }
}

The VERSION file content is:

1.2.0-dev.4

Also I have a tag 1.2.0-stage.5 in my repository (which later will be used as a fallback for the version bump).

Current behavior
standard-version suggests 1.3.0-dev.0.

Expected behavior
standard-version suggests 1.2.0-dev.5

Environment

• standard-version 9.5.0
• Node/npm version: v16.14.2

Additional context
Tried with JSON file instead of plain-text and it works as expected
