compose: Update Microsoft.Search/searchServices API version to `2025-02-01-preview`

[JeffreyCA]

API version 2025-02-01-preview adds a new endpoint property in the form https://<name>.search.windows.net: reference.

It doesn't seem to be completely rolled out yet, but once it is we can use it in our generated Bicep and resource metadata instead of the current approach of relying on the resource name and adding the https:// and .search.windows.net prefix/suffix ourselves.
