docs(vpa): Remove redundant `in-place` reference from `"Auto"` updateMode

This commit removes the now redundant mention of `in-place`
capability from `"Auto"` as the currently released version `v1.4.0` does
not instrument `in-place` updates as an `"Auto"` default strategy.

As of now, `"Auto"` preserves it's behavior to perform `"Recreate"` when
specified.

There is a separate `updateMode` (the `"InPlaceOrRecreate"`) specified
within the `quickstart.md` guide that handles `in-place` updates.
