Diagnostic settings API outdated

[verschaevesiebe]

Bicep version
0.32.4

Describe the bug
Microsoft.Insights/diagnosticSettings@2021-05-01-preview still only has an older version available.
It's the only resource triggering the "Use a more recent API version for 'Microsoft.Insights/diagnosticSettings' '2021-05-01-preview' is 1343 days old. (should be no more than 730 days)

To Reproduce
Create a Microsoft.Insights/diagnosticSettings@2021-05-01-preview resource and enable all bicepconfig settings.

Additional context
Can someone give me more context on how resources are "managed" ? I assume that every resource get's it's own API updates. Is there a way to find all schemas for each api version somewhere ? Usually the documentation covers the latest versions (E.g some resources have 20 versions, what are the clear differences ?)

I've added the #disable-next-line use-recent-api-versions to ignore it but it still feels hacky.

Another question i have is why diagnostic settings are treaded like a provider on top of most resources instead of beign a child resource of the specific resource itself. E.g API Management.
