📚 Docs: --cache docs confusing

[dipunm]

What is the improvement or update you wish to see?

The statement:

When an option is omitted, reading and writing are both disabled

in https://github.com/vercel/turborepo/blob/main/docs/repo-docs/reference/run.mdx#--cache-options

Is confusing.

Is there any context that might help us understand?

I ran locally, and I believe it should say "reading and writing are both enabled". I thought maybe it meant if you omit the :rw part, but it just errors if you omit that (unless you use local:,remote:).

Does the docs page already exist? Please link to it.

Would you have found it clearer if it was:

When a caching source is omitted, reading and writing for that source are both disabled.

Re-reading this now, I can see how it can be clearer in a handful of ways. Thank you for pointing this out. Hopefully it will be clearer after #9489.
