Apart from being cleaner (and allowing removal at the point of export,
if that is ever requires), this also gives us a better guarantee that
the metadata is going to take effect.
By writing the `[General]` section ourselves, we avoid any issues that
may be present from a user constructing the file (incorrectly)
themselves, such as multiple `Title:` entries or a malformed `[General]`
marker.
The main goal is to ensure that the name is updated to what we expect it
to be.
