No registered resource provider found for location 'westeurope' and API version '2024-03-01-preview' for type 'flexibleServers'.

@alex-frankel sorry to tag you again but I really think this is serious issue. Almost every API I try to increase the version reports such version is not available when you try to deploy. Bicep was suppose to fix these things by providing reliable data not the other way around.

### Bicep Repro

_No response_

### Confirm

- [x] I have read the troubleshooting guide and looked for duplicates.

No source file, test, or entry point is named. Start by checking the Microsoft.DBforPostgreSQL/flexibleServers resource and comparing the requested 2024-03-01-preview version with the supported versions listed for westeurope. A useful outcome would require a reproducible Bicep deployment and confirmation of which API version is actually available.
