Replace list of report reasons on user profiles

[0x84f]

A GMT brought up that the current report reasons listed on the profile are a bit redundant and have a greater chance of users submitting reports that go through to invalid channels, after a Discord discussion in osu!internal this new listing was agreed upon between the team.

For ease of access I'll include the proposed list here as well:

• Cheating
• Using multiple accounts
• Inappropriate chat behaviour
• Inappropriate user profile
• Other

Basically opening a GitHub issue so it's easier to track dev/peppy discussions around changing this.

This is fine to go ahead with IMO.

Do we want to preserve the existing enums (and point them to new meanings) or make new ones?

[peppy]

Either or is fine, IMO. Whatever requires the least migration effort.
