Add org-wide continuous testing for content

To include checks for things such as:

• Spelling checks
• Sensitive content flagging
• Basic formatting
• Trailing whitespace / end-of-file issues

This turns out to be challenging to achieve.

GitHub includes documentation covering required workflows which are now no longer available (see notes near top of documentation here).

Starter workflows are available but appear to require a GitHub specific interaction and implied source control through the web interface of GitHub (docs for this are located here). These boil down to workflow templates at an organizational level, which is I feel different from org-wide testing enabled through a single software component. (docs for this are located here)
