[DOCS] Add version compatability and alias errors to restore snapshot guide

[jrodewig]

We should add the following errors to the Restore a snapshot guide:

Version compatibility errors

• [my_repo:my_snapshot/id] the snapshot was created with Elasticsearch version [x.y.z] which is higher than the version of this node [x1.y1.z1].
  --> Ensure cluster compatible.

• The index [my_index/id] was created with version [x.y.z] but the minimum compatible version is [x1.y1.z1]. It should be re-indexed in Elasticsearch x1.y1 before upgrading to x2.y2.z2.
  --> Ensure index compatible.

Alias-related errors

• index and alias names need to be unique, but the following duplicates were found [my_alias(alias of [my_index/id])]
• index, alias, and data stream names need to be unique, but the following duplicates were found [my_alias(alias of [my_index/id]) conflicts with index]
• alias [my_alias] has more than one write index [my_index_1,my_index_2]
• Invalid index name [my_index], already exists as alias

--> fixing aliases issues. Index and alias cannot be the same, and single alias cannot be pointing to multiple write indices.
