Pluralize

[methodofaction]

This PR pluralizes "Corrected document" based on the number of preceding docs.

Includes a small change placing contract in a single line, where it was like this before:

Contract
XXX-001
2021-02-01

It is now displayed like this:

Contract
XXX-001 · 2021-02-01

Which is more in line with what we are doing with the preceding documents.

@cavalle I've struggled to find why my PR is not passing tests despite doing go test ./... --update, perhaps you can give some insight?
