docs(run): fix passthrough arg behavior (#10167)

### Description

Updating documentation around pass through args to address #8089.

This has been our behavior since 1.0 and I believe changing it would
require a major semver bump.

We pass any pass through args to tasks that match the name of one of the
tasks provided to the `turbo run` command. I believe this makes sense as
your `test` tool probably accepts different arguments than your `build`
tool so if `turbo test -- --coverage=true` passed `--coverage=true` to
not just `jest`, but also `esbuild` which might error when given that
argument. If you did want it to be passed to build you can achieve this
by running `turbo build test -- --global-flag`.

### Testing Instructions

Added a unit test for this behavior. 

Also spot checked that this has been the behavior since 1.2.0 (earliest
version I can get working without too much work). Tested by running
`pnpm turbo run test --filter=@repo/ui -- passthru`

1.2.0
