…azel-contrib#1443)

* fix(builtin): remove local execution requirement for npm_package assembly action

Removing the execution_requirement of local execution as this ends up being more
costly when in a fully remote cachable tree of actions.

* fix(builtin): add an indentifying mnemonic to create_package run action

Adds a mnemonic to npm_package's create_package run action to allow
it to be more easily/better identified.
