Fix link in Draupnir docs

Patch contributed by JulianF.

Update borg 1.2.5 -> 1.2.6

add matrix_synapse_oidc_enabled and matrix_synapse_oidc_providers vars

add `ensure-users-created` tag alongside with `ensure-matrix-users-created`

Seems like we don't necessarily need to use a public URL for `SYNCV3_SERVER`.

This possibly helps setups that were having trouble when `SYNCV3_SERVER`
was a public URL (e.g. `https://matrix.DOMAIN`), as described in:

This reverts commit fd6daf3d24.

Looks like v1.2.5-1.8.2-2 supposedly offers Postgres v16 support,
but does not work well with it and will need additional work.

Rate limit docs had a issue due to the wrong request type by accident. This was not noticed due to both bots can work with rate limits. Synapse Admin links where also bugged but now fixed.
