Missing characters after 1.5

[NekoDrone]

Issue

Currently, the database is only populated for characters up to Honkai: Star Rail version 1.5.

From each character's listing on the Honkai: Star Rail fandom, we will need the following information for the following characters:

Data type

You may find this template under ./helpers/characters.ts.

The full type definition is here:

interface CharacterInfo {
    element: CombatElement,
    name: string,
    path: CharPath,
    rarity: number,
    starting_hp: number,
    starting_atk: number,
    starting_def: number,
    starting_spd: number,
}

The characters requiring this information are:

• [ ] (1.6) Ruan Mei
• [ ] (1.6) Dr. Ratio
• [ ] (1.6) Xueyi
• [ ] (2.0) Black Swan
• [ ] (2.0) Sparkle
• [ ] (2.0) Misha
• [ ] (2.1) Acheron
• [ ] (2.1) Aventurine
• [ ] (2.1) Gallagher
• [ ] (2.2) Robin
• [ ] (2.2) Boothill
• [ ] (2.3) Firefly
• [ ] (2.3) Jade

Additionally, please ensure the the file at ./helpers/characters.ts is updated with the new characters as well.

Acceptance Criteria

The issue is resolved when the characters listed above have their initial data populated in both the database and in the reference file.
