Consider renaming `AddOracleDatabase`.

[IEvangelist]

There are several variations of database server resources modeled within .NET Aspire. Many of the APIs that exist support chaining from a container/server resource to add a database. The AddDatabase extension lights up for these resource types. Consider the following names:

• SQL: AddSqlServer and AddDatabase
• MySQL: AddMySql and AddDatabase
• Postgres: AddPostgres and AddDatabase
• MongoDB: AddMongoDB and AddDatabase

Currently, this API stands out as the AddOracleDatabase adds the server resource as a container but not a database as the name might imply:

• Oracle: AddOracleDatabase and AddDatabase

For the sake of consistency, I propose a rename API as follows:

• Oracle: AddOracle and AddDatabase

-IResourceBuilder<OracleDatabaseServerResource> AddOracleDatabase
+IResourceBuilder<OracleDatabaseServerResource> AddOracle

Good point! Obsolete the old API and add new one.
