chore: fix dotnet -p deprecation warning (#18632)

# Overview
Replace usage of `-p` with `--project` for `dotnet run` to resolve deprecation warning (`NETSDK1174`).

This appears during AWS CDK usage under .NET (C#, F#).

The full error message is similar to the following example:

> The abbreviation of -p for --project is deprecated. Please use --project.

> The use of -p in dotnet run is deprecated because of the close relationship dotnet run has with dotnet build and dotnet publish. In dotnet build and dotnet publish, p is used to set MSBuild properties. This deprecation is the first step in aligning abbreviations for these three commands.

Resolves #18092
