Reapply Redis password

[Alirexaa]

Description

Add Password To Redis (dotnet/aspire#464) has been reverted because of [WebToolsE2E][Aspire] Using ‘azd up’ to deploy aspire starter with redis project fails with error: generating bicep from manifest: argument 1 cannot contain connection strings, secured parameters, or secret outputs. Use environment variables instead. (dotnet/aspire#7429).

This PR addresses the mentioned issue by changing the container entrypoint and providing the password from an environment variable.
