Create-db.sh incompatible with the latest version of mssql/server:2019-latest

[MicahBredenhorst]

When initializing from a template using:

dotnet new epi-alloy-mvc --name alloy-docker --output ./alloy-docker --enable-docker

You get an error that /opt/mssql-tools/bin/sqlcmd does not exists. This is because the newest version of mssql/server:2019 has its tools located at: /opt/mssql-tools18/bin/sqlcmd

It is still an open issue in github on mssql-docker, should the create-db.sh script be adjusted as a result of this change?

We have updated our documentation to say the following:

In SQL Server 2022 (16.x) CU 14 and later versions, container images include the new mssql-tools18 package. The previous directory /opt/mssql-tools/bin is being phased out. The new directory for Microsoft ODBC 18 tools is /opt/mssql-tools18/bin, aligning with the latest tools offering. For more information about changes and security enhancements, see ODBC Driver 18.0 for SQL Server Released.

Based on that answer, IMO, the script must be updated to the new location/tooling.
