phase: rename the requirement for internal-phase (BC)

The previous requirements covers both `internal` and `archived` phase.  However,
the `archived` phase is not ready for usage (while the internal one is mostly
ready for years). So we split the archived on in a dedicated requirements (see
previous changeset for details) and rename the one for internal-phase. This will
avoid older client trying to use the archived phase on `internal` only
repositories.

Since the requirements stayed experimental since its introduction. It seems
fine to drop the previous version.
