Look at possibility of scheduling `npm linkinator` for scheduled runs

[polandll]

I added linkinator to package.json. But I'd like to consider scheduling a regular run of it.

In the scripts list

"build:linkinator": "npx linkinator https://stargate.io/docs --recurse --skip ' http://localhost?'",
"build:local-linkinator": "npx linkinator ./modules/*/pages --recurse --skip ' http://localhost?'"

"linkinator": "^3.0.3", in the repository list
