Improve naming in a file with exported settings

### Issue Details

STR:
1) Open extension's settings
2) Click 'Export settings'
3) Open the exported file

The names of the settings in the file may not be clear to users. For example `allow-acceptable-ads` refers to the `Block search ads and websites' self-promotion` setting and has nothing to do with [acceptable ads](https://adblockplus.org/acceptable-ads).

### Proposed solution

Adjust the names of the settings in the exported file to match the names of the settings in the extension.

### Alternative solution
