[Tagging] Mechanical edit - Musical instrument

[Matthijs Melissen]

Dear all,

As you remember, I had proposed to automatically change all objects tagged with
shop=musical_instruments into shop=musical_instrument.

I had asked permission from the Data Working Group for this edit.
Today, I received an answer from the Data Working Group. They
indicated that they do not usually give explicit permission for
mechanical edits. However, they do not see obvious flaws with the
proposal.

Therefore, I have carried out this edit today.

Kind regards,
Matthijs
