Add monitoring.yaml to all packages in the repo

A monitoring.yaml file is used by Solus package to enable automatic scanning for new releases and security advisories. It is included in the directory of the relevant packages alongside package.yml, pspec*.xml, and MAINTAINERS.md. Read more about it on our Help Center.

You can find all the packages that are still without monitoring.yaml by running this command:

# Replace solus-builds for the directory you have in your system
cd solus-builds/packages
find . -maxdepth 2 -mindepth 2  ! -exec sh -c 'test -e "$1"/monitoring.yaml' sh {} \; -print

Guidance on fixing

• One commit per package, but multiple commits (packages) on one Pull Request is OK
• No need to bump and rebuild the package, our build tooling does not read monitoring.yaml
• Be sure to check for a CPE, even though many packages will not have one.

The list

• 3070 2937 2686 2604 2300 1923 1898 1717 1419 1045 16 packages left

Run the provided find command from solus-builds/packages and compare its results with the linked package list. For each remaining package, inspect its package.yml, pspec*.xml, and MAINTAINERS.md, read the Help Center guidance, and add monitoring.yaml with a CPE when applicable. Verify that every listed package now has the file without rebuilding packages.
