Release 2.0.3 not available on repo.magento.com

Nobody has claimed this yet.

Last week version [2.0.3 was released](https://github.com/magento/composer-root-update-plugin/releases/tag/2.0.3).
However, the package is not available on repo.magento.com:

```
% jq .repositories composer.json
{
"0": {
"type": "composer",
"url": "https://repo.magento.com/"
}
}

% composer show --format json --available magento/composer-root-update-plugin | jq -r .versions
[
"2.0.2",
"2.0.0",
"1.1.2",
"1.1.1",
"1.1.0",
"1.0.0",
"0.1.1",
"0.1.0"
]
```

What is the reason? When can we expect it to be available?
Was it tagged by mistake in the open source repo and will become available when Magento 2.4.6 is released?

Start with the 2.0.3 release and the composer.json repository configuration shown in the issue, then run the provided composer show command against repo.magento.com. Determine why the released package is absent and document when it should become available or whether the tag was premature.
