Remove npm-publish-link-builder.yml and merge with npm-publish.yml

[aminjafer-n3o]

I need to come back to this and merge both into the same npm-publish but there are two challenges:

• The command for npm version is requiring the additional flag for --git-tag-version when trying to publish the link builder repo. We can maybe add this flag to the npm-publish.yml anyway since it should not affect current functionality of the workfow.
• The project structure for the Link Builder is quite different than for n3ojs and does not require the second prepack step in the npm-publish.yml workflow. We might need to adjust the npm-publish.yml to have a second optional parameter set to true by default and when invoke from linkbuilder we set it to false, then use this in the if condition for the second prepack step in npm-publish.yml.
