docs: Fix duplicated word in runtime dependencies guide summary (#13630)
### Description
Fixes a doubled word in the `summary` frontmatter of the "Coordinating
development runtime dependencies" guide. The word "with" appeared twice,
The second one is the Turborepo `with` configuration key, which had lost
its backticks and read as a repeat.
Wrapped both config keys in backticks so the summary reads naturally and
matches how the guide body and other guide summaries format code.
