Broken link in documentation for translators

[MichaelTimbert]

In the documentation /docs/Translation-translators.md redirect to zonemaster/docs/internal-documentation/maintenance/Instructions-for-translators.md that doesn't exist. It must link to docs/internal/maintenance/Instructions-for-translators.md

Furthermore the documentation in docs/Translation.pod already points to the correct documentation.

we have two solutions:

• correct the link in docs/Translation-translators.md
• delete docs/Translation-translators.md

Question, for this kind of link between repository, which branch should we target (master or develop)?
