Upgrade to NixOS 24.05

To resolve database collation version mismatches ("The database was
created using collation version 2.38, but the operating system provides
version 2.39."):
$ sudo -u postgres psql
> \c hass
> REINDEX DATABASE hass;
> ALTER DATABASE hass REFRESH COLLATION VERSION;
[ Repeat for all databases (except special database template0) ]
