chg: [iep2] MANIFEST updated, set version value to string (all are strings in taxonomies)

Notes: $text feature is something not implemented currently in MISP (IEP is the only taxonomy having variable
values). Maybe having a set of police like SPDX license module would help to have more generic agreement.
