build: update Dockerfile and project file references

- Ignore the `.dockerignore` file in the git diff
- Update the base image in the `Dockerfile` from `dotnet/runtime:6.0-alpine` to `dotnet/runtime:8.0-alpine`
- Adjust the build configuration in the `Dockerfile` to use the `BUILD_CONFIGURATION` argument
- Update the `dotnet restore` command in the `Dockerfile` to remove the directory path
- Update the build command in the `Dockerfile` to use the `BUILD_CONFIGURATION` argument
- Adjust the publish command in the `Dockerfile` to use the `BUILD_CONFIGURATION` argument and disable the app host usage
- Remove the user creation and ownership changes in the `Dockerfile`
- Update the project file `YoutubeLiveChatToDiscord.csproj` to include a reference to `Microsoft.VisualStudio.Azure.Containers.Tools.Targets` version 1.19.5
