Use Material save icon in activity_profile

[thgoebel]

Use the save icon from the Material icons instead of the outdated Holo icon.

The source of the icon is Android Studio's "New->Vector Asset ->Clip Art".

By the way, what's the story behind this icon? :)

haha 🙈
It's a leftover from earliest times of ProtonVPN android (pre-release). I used random icons at development time for drawer items because the correct ones were not yet decided. And somehow one .xml managed to get into repo. Will remove it, thanks for finding 😄

And thanks for your merge requests 👍 Like before, we'll keep them open until they are integrated and merged locally.

Ah, I see 😄. While you're at removing icons, the ic_check_legacy looks unused as well.

Okay, great!
