[yew-devel] [PATCH proxmox-yew-comp v2] apt_repositories: Add context to conflicting string with plural form

[Maximiliano Sandoval]

The combination of `msgid` and `msgctxt` uniquely identifies a
translatable string. At the moment there is a message:

```
msgid "Warning"
msgstr ""
```

that conflicts with
```
msgid "Warning"
msgid_plural "Warnings"
msgstr[0] ""
msgstr[1] ""
```

Normally, `msgmerge` or similar will merge messages containing the same
`msgid` and `msgctxt`, but in this case these two cannot be merged as
one has plurals forms and the other does not. On the app-side one will
be retrieved with `gettext("Warning")` while the other by
`ngettext("Warning", 1)` which explains why they can't be merged.

Additionally, xgettext will throw the following error message:

```sh
$ xgettext proxmox-yew-comp.pot proxmox-widget-toolkit.pot
proxmox-widget-toolkit.pot:2080: duplicate message definition...
proxmox-yew-comp.pot:187: ...this is the location of the first definition
xgettext: found 1 fatal error
```

By adding a context, we can go around the issue without the need to
replace either string.

More info on contexts can be found at [1].
