Clarification for local mounts in the context of DR

[lucymhdavies]

The docs were unclear on this point, so @russparsloe and I looked into it.

Local mounts are indeed replicated to DR secondaries.

This is the opposite of what it says on https://developer.hashicorp.com/vault/tutorials/enterprise/performance-replication#disaster-recovery

Local backend mounts are not replicated and their use will require existing DR mechanisms if DR is necessary in your implementation.
So that page will also need updating

The following were all configured on a DR primary, then replicated over to a DR secondary. That DR secondary was then promoted to a primary.

@lucymhdavies thank you for the PR! If you make more docs changes in the future, they don't need changelog entries. You can use the "pr/no-changelog" label to make the build check pass.

Aha! Good to know, thanks. I'll keep that in mind for my next doc update :)
