Fix ProjectTemplate build steps with new JDK

[sebastienros]

Fixes #55975

1. By running this step only on CI the ProjectTemplates local build doesn't work with a missing artifacts\obj\Npm.Workspace\Release\packagesToPack.json file.
2. Bump gradle because teh current version is not compatible with JDK 22
3. Reacted to gradle breaking changes: new maven plugin and DSL changes

After these changes eng\build.cmd -all -pack -configuration Release works on my machine.

I kept this because building the project keeps changing it back

[sebastienros]

Got warnings without that

[sebastienros]

This is the internal task that needs to be invoked to trigger publishing

IT's very probable I forgot something, didn't know what gradle was before this PR. At least I checked that the expected assets were generated:

The pom file:

Does the CI test the packages and their dependencies? The DSL wrt these dependencies has changed (compile, runtime, test) and I wonder if the final packages have the correct dependencies after this PR, and not too many (like test-only dependencies).

Thanks @sebastienros!

This is blocked on dotnet/dnceng#3093
The CI doesn't pass on macOS and linux because the JDK is too old and the opposite problem happens, which is they don't support the new Graddle.

@sebastienros is this still blocked? If so, can you please update the milestone of the associated issue so that it isn't sitting in an old milestone?

[javiercn]

@sebastienros is this still relevant?

This seems to be obsolete now. The ProjectTemplates build no longer runs only in CI since d65f5c4 and we upgraded Gradle in 5bfe483 and 6b29463 so that it works with newer JDK.
