Make a page for module resolution errors

In an internal discussion around https://github.com/loadimpact/k6/pull/1439 it was proposed the messages get smaller, but link to specific documentation pages that explain possible reasons and solutions to the problems.

Similar thing in [SqlAlchemyErrors](https://docs.sqlalchemy.org/en/13/errors.html#interfaceerror) and [AWS solution pages](https://aws.amazon.com/premiumsupport/knowledge-center/troubleshoot-rds-swap-memory/).

Start by reading the discussion in linked pull request #1439 and compare the referenced SQLAlchemy and AWS solution pages. Define the documentation page around the possible causes and solutions for module resolution errors, then confirm that the relevant error messages link to it.
