Previously, the restore API snippet included a `include_global_state` value of `true`.
Some users copy and paste the code example verbatim, updating only the index and
snapshot value names. Running the snippet could inadvertently wipe out a
cluster's current ILM policies, index templates, and ingest pipelines.
This change updates the snippet to use a `include_global_state` value of
`false`. It also adds a callout that better describes impacts of
using a `include_global_state` argument of `true`.
