BACKLOG-23333: Pack from dist/build/ and deploy dist/*.tgz

[baptistegrimaud]

JIRA

https://jira.jahia.org/browse/BACKLOG-23333

Description

Packing

Update the pack-project.js script (used by yarn build) to pack the content of the dist/build/ folder into a dist/<project>-<version>.tgz file.
If the dist/build folder does not exist, fallback to the previous behaviour and pack the root directory directly. This way, we can first release a new version of @jahia/scripts that we can then use in https://github.com/Jahia/luxe-jahia-demo, https://github.com/Jahia/npm-create-module, etc.

Deploying

Similarly, update the deploy.js script (used by yarn deploy and yarn watch) to deploy the dist/<project>-<version>.tgz file if dist/build/ exists. Otherwise, it expects the archive file in the root folder of the project.
