translation.wording_shape: A member is written in the wrong shape for what it words

A member is written in the wrong shape for what it words.

Area 10, Configuration; not declinable; the next step is usually the agent's.

How a message is worded follows its fields: a plural count needs a wording for each plural form, so a plain string is the wrong shape.

example

translations {    parcels: "{count} colis"}

jadpo checkcheck failed: 1 error, 4 files

error parcels is a string, but needs one wording for each value or plural form

--> domains/shipping/translations/fr_fr.jadpo:2:5

  |2 |     parcels: "{count} colis"  |     ^^^^^^^ needs a block with a wording for each plural form: `one`, `many` and `other`

reason: How a message is worded follows its type: no choice, a plain string; one enum field, a wording for each value of the enum; one PluralCount field, a wording for each plural form of the language.
next: Write parcels as a block with a wording for each plural form: one, many and other (agent)
