Add additional metadata to GitHub repo projects and integrate it into the site

[twocaretcat]

We can add a lot of additional metadata to project READMEs like:

• category: The type of project (ex. App, Extension, Website, etc.)
• languages: A list of additional languages to append to the language list provided by the GitHub API (ex. GraphQL)
• technologies: A list of technologies used (ex. React, Gatsby, etc.)
• tools?: A list of tools used (ex. Git, GitHub, Linux, etc.)
• schemaType: A @type property to use for the structured data on the corresponding project page (ex. SoftwareApplication, MobileApplication, or WebApplication)
• schemaApplicationCategory: An applicationCategory property to use for the structured data on the corresponding project page (ex. GameApplication, TravelApplication, ShoppingApplication, etc.)
• schemaOperatingSystem: An operatingSystem property to use for the structured data on the corresponding project page (ex. Windows, Linux, etc.)

Other information, we can get via the GitHub GraphQL API, like:

• size and version of the latest release

We can use this information for things like:

• automating project recommendations on the resume
• adding additional information to structured data on project pages
