Improve name of file with exported list of exclusion sites

### Issue Details

Currently, when exporting a list of exception sites, the file is called `exclusions-2023_09_04-00_47_21`, but I would like it to have a descriptive and uniform name on any device.

### Proposed solution

Name the file with the exported list of exclusion sites like this: `adguard-vpn_chrome-extension_website-exclusions_2023-09-04_22-41-27`.
