http-client.env.json incorrectly copied to publish output directory

[Varorbc]

the http-client.env.json file is incorrectly copied to the publish output directory during project deployment.

This file is an environment configuration file for the HTTP Client tool and should not be treated as deployable content. Its presence in the publish directory is unnecessary and potentially exposes environment-specific configuration details.

I'm unsure if this is the correct repository to report this issue.

This should be controlled by ASP.NET. I'll move to dotnet/aspnetcore.

**/*.json files are being automatically included as Content items.

These JSON Content items have CopyToPublishDirectory=PreserveNewest, which means they should be included in the publish output directory (though not for single file, for some reason).

A workaround for now is to set this yourself:

<ItemGroup>
    <Content Update="http-client.env.json" CopyToPublishDirectory="Never" />
</ItemGroup>

When investigating this, we should review the contents of the publish folder for any other files that should be omitted.
