[FIX] website_event: make `Attendee #` translatable

On the website,
when registering for an event with ticket,
the placeholder `Attendee #` could not be translated,
as `t-att` attributes are not translated.

An alternative is to put the string to translate
in a `t-set` node, which can be translated, and
to use the variable assigned in this `t-set`
in the `t-att` attribute.
