Context

in order to ease CI builds and konflux integrations, and have standardise with other observability plugins we need to migrate away from yarn and use npm

Outcome

The monitoring plugin uses npm instead of yarn for development and in Dockerfiles

Steps

• Migrate the yarn.lock into a package-lock.json, check the resolutions that were added to resolve CVEs
• Update the makefile to remove yarn calls
• Remove yarn specific installations from the Dockerfiles
• Update docs that have yarn references
