🐞📚 fix errors with frontmatter for syntex docs

- validation errors with `ms.prod` frontmatter prop:
  - invalid value set - value for `ms.service` used as `ms.prod` value
  - can't have both `ms.prod` & `ms.service`: mutually exclusive
  - removed value from docs & moved to docfx.json for mass set
- added missing `ms.date`
- fixes to other docs to account for above changes
