[richardolsson]

Description

When editing an existing tag, either from the tag select widget, or from the new tags page, the submit button of the edit tag dialog says "Create" or "Create and apply" when it should say "Update" or "Save" or something like that.

Steps to reproduce

Case 1

1. Go to https://app.dev.zetkin.org/organize/1/people/2
2. Click on "Add tag"
3. Click the pencil on any tag to edit

Case 2

1. Go to https://app.dev.zetkin.org/organize/1/tags
2. Click on any tag

Expected Behaviour

The submit button should say "Save" or "Update".

Actual Behaviour

The submit button says "Create" or "Create and apply".
