Rename the changelog tab on the branch view

[jeremystretch]

Plugin Version

v0.4.0

Proposed functionality

Rename the "Changelog" tab on the branch view to better distinguish it from the other tabs (e.g. "History" or similar).

Use case

The changelog tab can be confusing to the user as it is not immediately clear how it differs from the other change-related tabs. (As with most other objects in NetBox, the Changelog tab displays a history of changes to the branch object itself, as opposed to changes to objects within the branch.)
