Why dependabot not support widen even though the docs stated it

[kiraware]

As the docs inform https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#versioning-strategy, there is widen in versioning-strategy. But why it says error like this The property '#/updates/0/versioning-strategy' value "widen" did not match one of the following values: lockfile-only, auto, increase, increase-if-necessary. I use Python Poetry as dependency manager.

This is my dependabot.yml

version: 2
updates:
  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "monthly"
    groups:
      dependencies:
        patterns:
          - "*"
    versioning-strategy: widen

Hi @kiraware - please see https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#versioning-strategy which details which versioning strategies are supported in which ecosystems. At this time, widen is not supported for pip.

Ah, as I expected, pip doesn't support widen versioning strategy yet. Thanks for your answer.

I use cargo and the docs say versioning-strategy is supported, but I get the same error:

Your .github/dependabot.yml contained invalid details

Dependabot encountered the following error when parsing your .github/dependabot.yml:

```
The property '#/updates/0/versioning-strategy' value "increase" did not match one of the following values: lockfile-only, auto
```

Please update the config file to conform with Dependabot's specification.
