👻 Refactor archetype table app column text (konveyor#1553)

On the archetype table, applications column, update the translation key
used to be plural aware via i18next:
  - When `count == 1`, use key `archetypeApplicationCount`
  - When `count != 1`, use key `archetypeApplicationCount_plural`

Net result is "1 application" and "3 applications" will be rendered. The
"(s)" suffix is no longer required.

Note: The app is currently using `i18next` v19. In current versions, and
therefore current docs, the count suffixes are different.
