Geo: Improve HA install docs

See merge request gitlab-org/gitlab!26542

Update docs for multi-project pipelines

Closes #209041

See merge request gitlab-org/gitlab!26560

The docs were mixing visualizations / graphs with
other multi-project pipeline features, which made it
difficult to manage now that some features are split
over different tiers. This splits visualizations into
a new section, which can be badged with it's tier,
while the rest becomes free (since 12.8).

Change inconsistent and vaguely worded “Prepare for the renewal”...

See merge request gitlab-org/gitlab!26718

Change inconsistent and vaguely worded “Prepare for the renewal” / “Prepare for renewal” to much more concise 'Prepare for renewal by reviewing your account'. The word 'review'/'reviewing' is used elsewhere already by the documentation.

Update index.md, added the missing word 'the'

See merge request gitlab-org/gitlab!26713

Geo - Make registry table SSOT for Uploads

See merge request gitlab-org/gitlab!25482

FileDownloadDispatchWorker looks only at the registry table
for things that have never been synced.

In order for the counts to be correct, we have to distinguish
between "never synced" and "failed" with "retry_count" being
"nil" for the former and "not nil" for the latter.

Feature flag is "geo_file_registry_ssot_sync".

Add skeleton loader to new packages list

Closes #208424

See merge request gitlab-org/gitlab!26176

* Add caveat that we don't support PG HA in secondaries
* Suggest ensuring the secondary cluster works without Geo first
* Add configuration to disable geo_logcursor on the PG read-replica node
  to prevent it from attempting to configure Rails if you don't have any
  Rails services explicitly enabled. Otherwise, reconfigure could get
  blocked on things like erroring on migrating databases even though you
  never asked to run geo_logcursor on the PG node.
* Add suggestion to run backend Rails services on backend app nodes

Enable caching for milestone issue counters by default

See merge request gitlab-org/gitlab!21554

We want to expose milestone issue counts to the API for
https://gitlab.com/gitlab-org/gitlab/issues/31289.

The current milestones page is also very slow -
it has N+1 for the same counters.

We want to cache these counters, but they depend on user,
which makes cache useless.

So this commit removes dependency on `user` variable for
milestone issue counters
