[Object Store] cbbackupmgr info fails due to new 'cloud_type' field

What's the issue?
In MB-42354 we added a cloud provide field to the archive version file, when performing an info at the archive level all files will be downloaded using a download pool. This means we won't update the provider type in the version file causing the info to error out because the staging directory is invalid.

Error getting archive information: existing staging directory is for another cloud provider, retry with another one or recreate the existing one

I haven't tested but I believe this will be an issue for collect-logs as well. Can confirm, is affected.

Note that this only happens after the first successful population of the staging directory, therefore, a temporary workaround until I've fixed the issue is to recreate the staging directory and re-run the sub-command.

What's the fix?
The '.backup' and '.info' files have special significance for cloud backups and are manually downloaded and excluded from being downloaded by worker pools (in the normal case i.e. when performing an operation at the repo level). However when performing an operation at the archive level they are not; we should detect and handle this scenario by populating the cloud provider field in the version file (along with any other missing fields).
