PLA-221 Rework PullRequestTest to work with non npm package managers

[quesabe]

Closes PLA-221.

Previous to this PR the test workflow can only operate with npm. In order to make it work with other package managers the following was done:

• move from npm-run action to a manually composed job with all steps replicating the npm-run action - the function is named setupNode; the node setup is configurable to be capable of working with npm, pnpm and yarn (with the help of projen internals).
• add arunScriptJob function that sets up a generic workflow job with the setupNode steps and a final command being run afterwards;
• utilise setupNode for lighthouse audit setup;
• update the PullRequestTest workflow to use the new functionality;
• update tests and templates accordingly.

This jobs completely replicates the npm-run action and adds functionality to work not only with npm, but rather pnpm and yarn.

@quesabe can we release it to *.*.*-canary version? So that @igorosip0v can play with it in real repo?

@gvidon, I guess we can. The workflow we have does not support such a variety, but I can do it manually.

BTW do we expect canaries to be rarely used or not? If we want a long lasting solution for canary releases maybe I should create a branch canary for such releases and configure the workflow... And for now is it ok to release from the PR branch? Otherwise I could set up the canary workflow first and then use it here, but it would slow down the advance with this PR.

Please let me know which path you consider more suitable.

@quesabe for now we don't plan frequent canaries, so lets go with manual solution. Please ping @igorosip0v on Slack when it is published.
