CI error because Bundlr changed name and their repo cant be reached

[erhant]

This affects both the testing & publishing workflow.

As a remedy:

• We pass tests locally.
• We create the build locally (at lib) and publish it to repo.
• We then run the workflow to directly publish NPM package using the library.

Note that pnpm install works locally, but not within CI environment? Perhaps --no-frozen-lockfile causes stuff to break?
