PRF stage: error in typed stage name and abbreviation

[opoudjis]

id = Pubid::Iso::Identifier.create(:number=>"1000", :publisher=>"ISO", :year=>2023, :stage=>:PRF)

id.typed_stage_name == Proof of a new International Standard International Standard

That is incorrect, it should be Proof of a new International Standard

This is also an issue:

id = Pubid::Iso::Identifier.create(:number=>"1000", :publisher=>"ISO", :year=>2023, :stage=>:PRF)
id.typed_stage_abbrev
=> "PRF IS"

The correct one should be:

• "PRF" for "PRF for International Standard"
• "PRF TR" for "PRF for Technical Report"
