The Nextcloud admin guide says that output buffering must be turned off
or otherwise PHP will return memory-related errors [1]. As the default
value for this PHP setting is 4096 and thus enabled the Nextcloud setup
is thus misconfigured by default. This misconfiguration will be shown in
the "Security & setup warnings" dialog for the administrator.
Fix this misconfiguration by setting "output_buffering=0" by default.

Closes#277206
The bug mentioned above was a symptom of the issue fixed here: when
opening the `forms` app which is installed via `extraApps` (or the
app store) the site wouldn't work because `.mjs` files had the wrong
Content-Type.
The actual problem got fixed already[1], however this config was not
used for stuff from `/nix-apps` & `/store-apps` which had their own
location section with only a `root ;` statement.
In fact, this setup isn't strictly supported by Nextcloud upstream[2],
so to fix this for good, I decided to follow the upstream suggestion for
app directories outside the server root, i.e. linking them back into the
store path.
This means that the module generates a new derivation now with
* `services.nextcloud.package` linked into it via `lndir`.
* under `nix-apps` is a symlink to the link farm containing all apps
from `services.nextcloud.extraApps`.
* under `store-apps` is a symlink to `/var/lib/nextcloud/store-apps`.
Since this is only used in the NixOS module that also configures this
location for imperatively installed apps, this seems an OK thing to
do.
Successfully tested the change on a productive Nextcloud 28.0.1 with
several apps installed via `extraApps` (`forms`, `cospend`, `maps`,
`user_saml` and a few more).

This makes sure we don't need any workarounds for running Invidious with a local
PostgreSQL database.
Changing the default user should be fine as the new init script for PostgreSQL automatically
creates the new user and changes the existing database's owner to the new user. The old user
will still linger and must be removed manually.

This fixes the following eval error:
```
error: nodePackages.node-red cannot be found in pkgs
```
when having `services.node-red.enable = true;` without specifying
`services.node-red.package`, just like the nixos VM test.
Follow-up of f509382c11, which attempted
to fix this as well.
Breakage introduced in 0a37316d6c.
* Always use PHP 8.2: at the time of writing, Nextcloud also suggests to
use 8.2 rather than 8.3 in the manual for v28.
One contributing factor is probably that all plugins need new releases
to declare PHP 8.3 support.
* Fix upgradeWarning for installing v27 now that v28 is out.
* Drop upgrade warning for v24. This one is EOL for quite a while
already, so right now everybody should've switched (or carefully
studied the release notes in case they were upgrading from <23.05) and
we can clean up the module a little bit.
v25 was dropped not so long ago, so if it's still referenced (because
somebody didn't declare `services.nextcloud.package` and has
`system.stateVersion = "22.11";`) it's appropriate to still give a
specialized error.
