CoC disables backup files due to a problem with a typescript
language-server (it becoming slow when the backup file is written,
triggering a `structureChanged`). But:
1. I want backup files
2. I do not use that language server
3. If I would:
1. I could disable backup files in a filetype plugin
2. The linked issue is from 2019 - no idea if this is still
present today
4. I don't think this issue is even a thing with a `&backupdir` that
does not include relative directories (which is the case for me)
So remove the lines disabling backups and go back to vim's defaults:
`nobackup` and `writebackup`.
