version meta field is always required again

BMM won't detect updates if the version is None. Since the previous schema required version to be None when using `fixed-release-tag-updates`, that meant that manual updates via PR wouldn't be detected.

 - *fixed-release-tag-updates*: (*Optional*) Set to `true` if your mod uses a fixed release tag and still wants to auto-update when modifying the underlying files. This can be useful for repositories with multiple mods, allowing you to have a release tag dedicated for each mod where you upload new versions. Note that:
   - Requires `automatic-version-check` to also be set to `true`.
-  - Requires that the `version` field is not set as the version will be extracted from the asset's upload date.
   - The `downloadURL` must point to a specific release asset using a link such as `https://github.com/author/repo/releases/download/my-release-tag/mod.zip`.
