Publish MoreDateTime package to NuGet.org

[Copilot]

The package was not being reliably published to NuGet.org or GitHub Packages due to incomplete workflow steps, a missing tag-based trigger, an outdated push endpoint, and a secret name typo.

Changes

MoreDateTime.csproj

• Bump <Version> to 1.4.0 to match the latest git tag

dotnet.yml

• Add tags: ['v*'] push trigger so publishing fires on version tag creation
• Complete the "Push Github package" step — it was registering the source but never calling dotnet nuget push
• Update NuGet push endpoint: https://www.nuget.org/api/v2/package → https://api.nuget.org/v3/index.json

manual.yml

• Add dotnet pack step outputting to $GITHUB_WORKSPACE/out
• Add "Push NuGet package" step targeting NuGet.org via NUGET_TOKEN
• Fix "Push Github package" step: typo GH_PACLAGE_TOKEN → GITHUB_TOKEN, consistent output directory, correct dotnet nuget push invocation
• Update NuGet push endpoint to v3
